Sustainable Swimwear Brands Are the Definition of Hot Girl Summer

Sustainable Swimwear Brands Are the Definition of Hot Girl Summer

The summer is here, and it's time to get ready for the perfect bikini beach season. You've got your sunscreen, sunglasses, towels, and snacks all neatly packed into a cute bag, but what about your swimwear? There are tons of options out there when it comes to picking out sustainable swimwear brands that will make you look good and feel great while protecting our planet.

The sun is shining, the water is warm, and you're going to want to spend as much time as possible by the pool or on a yacht (or both). But before you do, make sure your swimwear will be durable enough for all those hours in the sun!

If you're like me and spend your summers by the pool, then you know that finding a swimsuit can be difficult. You want something cute and functional but also sustainable! This is why I've compiled this list of my favourite sustainable swimwear brands to help all of you hot girls find what's right for you.

I'm sure we can all agree that summer is the best time of year. The sun shines, you get to wear shorts and tank tops, and it's a chance for us to recharge after an exhausting school year! But as much as we love those warm days by the pool or at the beach, some things about them leave us feeling guilty. 

Each day many tons of trash end up in our oceans and waterways from people who don't properly dispose of their waste. 

And even if you're using biodegradable sunscreen (which we recommend!), your body will still produce sweat which will eventually seep into the water when you exit the pool. So what do we do? First, we need swimwear that doesn't contribute to this pollution.

If you're looking for a way to show off your girl power while still being conscious of the environment, then sustainable swimwear brands are for you. The best part is that they can be found in all shapes, sizes, and prices! 

Even if you're not on vacation this summer, wearing these trendy suits will have people remarking about how "hot" you are. 

If it's not too hot outside where you live or if there's an upcoming event where dressing up is required (e.g., prom), go ahead and put one of these bikinis on! It'll be worth it when people ask where I get my suit from because they want to buy their own.

Whether you're at the beach, by a pool, or on vacation somewhere tropical and warm, swimwear is an essential part of any summer outfit. However, with so many options out there, it can be hard to know which brands are worth your money and time. 

You don't want to end up spending $100+ on something that falls apart after one season! So below, we've compiled a list of sustainable swimwear brands for all your summer needs - from bikinis to cover-ups.

If you're looking for swimwear that is both fashionable and sustainable, these brands are perfect. There are tons of options to choose from when it comes to eco-friendly swimwear, but not all of them will give you the best bang for your buck. 

You'll want something that's functional and chic! We've compiled a list of our favourites with some helpful tips on finding what works for you. So read on to discover which suits suit your needs.

Top Eco Swimwear Brands

1. Vitamin A

The Laguna beach-based brand boasts a lengthy list of sustainability efforts. For example, the brand's founder Amahlia Stevens patented its EcoLux fabric (a signature, sustainable weave made of superfine matte jersey), and stretch-ribbed EcoRib fabric is made from recycled nylon. 

Its strictly monitored factories are based in California, dedicated to fair trade, partnering with artisans for global production. In addition, most Vitamin A's patterns are digitally printed, which greatly reduces water waste (because it requires less wash and rinse cycles than the common wet-printing method). 

This also rids the need for screen print and colouring baths that create further waste. The list continues: Its headquarters and warehouses only use LED bulbs (cutting its electricity demand by 90 per cent) and are equipped with solar-powered fans, low-flow water fixtures, motion-sensor lighting, and 100 per cent recycled post-consumer-waste paper products. 

The brand's recent launch is a low-waste, versatile collaboration with Misha Nonoo, featuring one of our favourite fashion gals, Amy Julliette Lefévre. The riveting Sustainable Summer Getaway capsule is dipped in summer shades of sea green, sapphire, and rust and is specifically designed for "beach to après" on steamy summer nights.  

2. Hunza G

Originally launched in 1984, British swimwear label Hunza G has enjoyed a resurgence of popularity under the creative direction of Georgiana Huddart, sported by stylish women in sunny spots across Instagram. 

The brand's signature crinkle fabric is made and turned into swimwear all in the UK, keeping the production process small and local. They also use the excess fabric to create small runs off headbands and scrunchies, and the colourful swimwear is delivered in biodegradable, recycled and recyclable poly bags. Even better, Hunza G donates a portion of its profits to charities like Street Smart.

‘I was looking for tones that were warm and uplifting but a step away from neons, which we did last year,’ says co-founder and creative director Georgiana Huddart of the burnt reds, lavenders, emeralds and turquoises in the brand’s latest Majorelle collection, which nods to the tones favoured by Spanish architect Ricardo Bofill. 

The offering includes elegant strapless swimsuits and hoop-detail asymmetric bikinis, crafted in the London brand’s signature crinkle effect fabric, which is knitted in the United Kingdom’s Midlands.

Hunza G has long been a proponent of sustainable design, an ethos only emphasised during the Covid-19 pandemic. 'It's highlighted our need to modernise,' says Huddart. The label hosts a monthly Conscious Club meeting for its small team, looking at ways to innovate environmentally aware. 

In a bid to reduce waste, offcuts from the brand's designs are transformed into headbands and scrunchies, packaging right down to hygiene labels is sustainable and recyclable, and the label operates a no-plastic office. From 2022, it will also introduce recycled nylon yarn.

Sustainability is about changing the mindset right from the core of a company rather than just in a perforative way to sell your products,’ Huddart says. ’It’s exciting to see what can be achieved if everyone works together.’

3. Lokiki

From its textiles to mailers, Lokiki is firmly rooted in a mission dedicated towards sustainability—thanks to the initiatives of co-founders Jen Dwin and Jen DeLory. The brand's core fabric is Italian-made of recycled nylon from fishing nets. Each batch is created in small quantities (to reduce the carbon footprint) in New York City. 

And each suit is dual-layered for a supportive fit without any bulky padding. In addition, its shipping bags are constructed of recycled paper and printed with earth-friendly ink (as opposed to some inks that may break down into pollutant chemicals). 

The brand is also working towards 100 per cent compostable packaging materials for shipping and 100 per cent recycled paper handbags by the end of summer 2021. The founders also donate 4 per cent of profits to clean water funds, which may help provide filtered drinking water to those in need of work to clean up ocean waste to protect our sea life.

4. Ohoy Swim

'We often look at images of our mothers in their youth for inspiration,' says Anna Maria Nielsen, one half of Ohoy Swim, who founded the brand in 2016, with fellow Scandinavian and Dubai-based Henna Kaarlelah. The duo is inspired by outdoors activities, from surfing to diving, creating comfort-focused pieces but do not look like activewear. 

Low back swimsuits and bandeau bikini tops have a sensual, subtly sporty sensibility, and the brand also highlights the bow detail as a style signature. ‘It allows different body sizes to adjust fit simply,’ Nielsen says.

Ohoy Swim manufactures its swimwear in a Sri Lankan factory which took six months to find, which it directly supplies with Econyl from Italy. ‘We travelled to the island for surf trips, and while we were there, we discovered it is well known for its swimwear manufacturing,’ Nielsen adds. 

For spring, the brand has launched ‘Trails’, a collection inspired by the tones of nature, featuring Ohoy Swim’s first print, a Pointillist floral design.

5. Sanctuary

Sanctuary's mission statement is a call to action for greater eco-awareness. "With every new partner, Sanctuary requires that the brand focuses on sustainability, give-back components and inclusivity," says its creative director Debra Polanco. 

The brand specialises in jeans and has created a smart creation process to help undo the water-heavy creation process of denim. Ultimately, it also applies to its swimwear. Its three-point plan includes low-impact fibres, recycled plastics, and an advanced wash process. 

The brand partnered with Amerex Swim Group for its swim line, which has enabled Sanctuary's swim to consist of 90 per cent recycled materials. Fibres like linen and tencel use up to 20 times less water; non-toxic production processes reduce minimal waste and pollutants. 

Internally, the brand avoids plastics as a whole (from the office to photoshoots), and sources recycled paper wherever possible.

6. Away that Day

Fit is of the utmost importance to Ingemae Kotze, founder of the two-year-old sustainable swimwear brand. 'When I fit samples on my sisters and friends, I can instantly tell what makes them feel confident,' she says. Away that Day's Palma bikini top is a buyer's favourite, featuring U-detail hardware and uplifting shirred details. 

Bold tones, bow details, and exotic prints also inform the flattering designs inspired by travel destinations from Sorrento to Havana, Rio to Palma. 'The colour of a single flower can also influence a whole collection,' adds Kotze.

Away that Day's swimwear is designed in London and manufactured by a family-run supplier in Bali, specialising in Econyl, an upcycled yarn created from plastic waste dredged from the oceans. The brand's packaging is also plastic-free, and for S/S 2020, Kotze is developing a collection created using bamboo.

7. Sqorpios

"Sqorpios was born from the strong desire to create a brand that is sustainable yet sexy and modern," says founder Chiara Bransi. "We want to show the world that sustainability is something that can be joyfully integrated into our daily lives." 

Sqorpios fabrics are made from recycled plastics pulled directly from the ocean and landfills worldwide, including fishing nets and industrial plastic. It undergoes a cleaning and regenerating process that creates a new textile yarn resistant to oils, chlorine, and sunscreen. 

For every 10,000 tons of this Econyl material, the brand can save 70,000 barrels of crude oil and avoid 57,100 tons of CO2 emissions (according to its site). Sqorpios doesn't stop there: all of its swimwear accessories (like tags, labels, and liners) are also made from recycled materials. 

Plus, the brand produces small quantity stock to ensure that products sell-through and no materials go to waste.

8. Ack

The label's rhinestone-sparkling acid-hued bikinis have enchanted Instagram, but its founders are committed to more longevity than a fleeting Like. 'Being sustainable is a way of life, not a sales tool,' says Rebecca Larsson, who founded the label in 2017 with Alessandra Scorletti

The label does not have a bricks-and-mortar office, creates its swimwear by hand in Italy in small facilities and has total control of its supply chain. From the conception of a product to its distribution, everything we do supports our local economy,' says Scorletti, the former creative director of cult sunglasses label Retrosuperfuture.

'The aim was not only representing women in their real natural forms but also enhancing their beauty,' adds Larsson of Ack's brand mantra. This translates to disco detail bikinis, metallic bi-colour balconette tops with floral hardware and kaleidoscopic tie-dye swimsuits with seductive cut-outs. 

Larsson found a series of marble caves around her hometown in Tuscany to shoot a recent series of images featuring models surrounded by figurative sculptures. 'We are one of the unique regions in Italy to have both the sea and the mountains in the same context,' she says. 'Even though I love the sea and the beach, I've never felt it was the first pick for shooting locations.'

9. Swiminista

Andréa Bernholtz believes that being eco-friendly should never mean sacrificing luxury—which she proves with her line of cabana couture, Swiminista. “Swimwear takes you outside, where trash and pollution are in your face—or, you’re swimming in it,” says Bernholtz. 

“Our goal is to leave the environment cleaner than you found it so that our future is something we can be proud of.” The recycled-bottle-to-suit brand is created from sustainable fabrics made from post-consumer plastics (aka discarded plastics that have been cleaned and reimagined).

Prolonging the life cycle of plastics not only prevents adding more virgin plastics to landfills, but it also reduces the carbon footprint by slowing the production of polyethylene terephthalate (the most popular plastic used for clothing fibre). 

Swiminista also uses compostable bags and boxes for its orders. But the brand is most popular for its fully adjustable sizing range that spans from XS to XL, as well as its cohesive accessories (like this adorable matching sarong).

10. Evarae

Searching for a little Italianate inspiration? Sustainable swimwear label Evarae produces its versatile and subtly-detailed designs in an atelier near Lake Como. 

The label's Move.Dance.Swim collection has a hybrid sensibility, featuring swimming costumes, bralettes and leggings, allowing wearers to move seamlessly from, say, a Pilates class to poolside. One-pieces feature feminine puffed sleeves, two-tone fabrics and frilled details.

A respect for the environment lies at the brand's heart, which creates its pieces using Econyl, an upcycled yarn formed from the ocean's plastic waste, including carpet and water bottles. 

What's more, the label employs sustainable manufacturing practices, from waste-reducing digital printing to recycled paper clothing tags. In addition, 2% of Evarae's online sales are donated to selected charities each month, ensuring the label gives back to environmental and social projects close to its heart.

11. Hermoza

Hermoza's main goal is to make suits that don't require a single sacrifice—whether that's in terms of style, fit, or investment. The brand's care for the planet is consistent with its practices. 

All of its fabrics boast a high UPF; Made with a regenerated nylon fibre from pre- and post-consumer materials, its UV transmission is less than 2.5 per cent when exposed to both UV and UVB light. 

The environmentally friendly dying and cleaning process ensures no harmful toxins or chemicals are leaked into the environment. Hermoza even insists that its suits are significantly resistant to wear and tear—even with the most intense use like water sports. 

The recycled fabric is durable enough to resist abrasions and chlorine and body lotions and oils so that nothing affects its vibrancy. All of this combined was enough to make Oprah a fan. The Genevieve was featured in O magazine and, obviously, anything Oprah-approved has to be great.

12. Tona

For stylist Tona Stell, inclusive sizing isn't an afterthought; it's an intrinsic intention. So when Stell launched her eponymous swimwear brand in July, she modelled her pieces on a UK women's size 16 and a FF bra cup, ensuring that every curve and contour of the female body was considered in the sampling process. 

The result is a series of eye-catching pieces, from underwired to welled bikinis with a high leg or high waist brief to vivid sporty bralette tops in vivid florals or Op Art checkerboard available in a spectrum of sizes. 

Each of Tona’s designs, which are encouraged to be worn with a mix and match aesthetic, is crafted using eco-aware fabrications, including bespoke organic cotton and Ecoynl, and is boxed using recycled packaging. Swim sporting conscious design in every stitch.

13. Zulu & Zephyr

With nearly a decade as one of Australia's favourite swim brands, Zulu & Zephyr is dedicated to its long-term sustainability efforts in several ways. "Since the launch of our Econyl swimwear in 2020, we have saved 28,000 barrels of crude oil and 26,040 tons of CO2 emissions," shares the brand in an interview. 

Econyl is a type of regenerated nylon that sells its textiles for fashion, sportswear, and swimwear. The covetable brand also partners with Healthy Seas to support marine protection and uses organic cotton. In addition, the brand is working towards plastic neutrality and donates one per cent of gross annual sales to 1% For The Planet.

14. Vanessa Sposi

'I believe in a sustainable approach, intending to provide modern classics – pieces that stand the test of time, pieces that collect summers,' says swimwear designer Vanessa Sposi

The founder of her ethically-made and eco-conscious eponymous beachwear brand, which combines swim with chic resort silhouettes, designs her pieces in Paris, weaves them in Italy and manufactures them in Portugal. 

Pieces, which include pared-back asymmetric one-pieces, leopard print bikini tops in bold triangle silhouettes or sporty narrow strap designs, and bottoms with a V-brief or high waist, are crafted using regenerative, organic, renewable and recycled fabrics, including Econyl. 

Silhouettes also have another feel-good factor: swimwear styles are infused with skin-nourishing Antioxidants rich in Vitamin E and soothing Aloe Vera to moisturise the skin when you've had a day soaking up the sun.

15. PQ Swim

PQ Swim sources fabrics that are both recyclable and biodegradable. Its packaging, tags, and labels are all made out of recycled paper. “Just like you, PQ cares to help preserve the future of our planet,” says its CEO, Amber Delecce. 

"We're always trying to stay on the cutting edge with technological advances that help reduce waste and energy use whenever possible." For example, its lyrica fabrics are made of a recycled polyamide (raw material regenerated out anything from old carpets to manufacturing waste) blended with biodegradable nylon

Ten per cent of PQ's proceeds from its Eco capsule (which was so popular it sold out, so stay tuned for restocks) are donated to Coral Vita, a company dedicated to restoring our ocean's dying coral reefs.

16. Ayla

Ayla's playful, feminine designs instantly conjure up feel-good holiday vibes and memories of cocktails on the beach, which was exactly the aim when London-based founders Kirsty Ames and Heidi Sommerau started the label – the idea was dreamed up while they were on the beach in Tobago. As a result, many of their collections are inspired by the Caribbean islands. 

Bikinis and one-pieces feature signature clashing colour frills and metallic thread detailing to contrast soft, tie-dye patterns. Their sustainable swimwear range is created from recycled fibres, while their sarongs are made with Cupro, a by-product of cotton that would normally be thrown away.

17. Momma

"Whether or not Momma was going to be sustainable was never a question for me," says its founder Jackie Robinson, adding, "it's just the right thing to do." The designer decided to use recycled nylon for its superior stretch and feel. 

"After testing hundreds of swatches on our journey to find the right fabric, we ultimately made our own custom blend for peak comfort," says Robinson. The original fabric is 80 per cent recycled nylon and 20 per cent spandex

Every suit is wrapped in biodegradable plastic, our tissue and stickers are recyclable, and our mailers can be recycled as you would grocery bags. Momma also makes donations to support One Tree Planted (which plants one tree in a US National Forest for every order purchased) and the United States Forest Service. 

Comfortable, multifunctional, and confidence-boosting suits are what you can expect from the inclusive brand. "We love to appeal to women of all shapes, sizes, and ethnicities, and our customers reflect that."

18. Peony

Family-run Australian swimwear label Peony takes its name from the blooming peonies in founder Becky Jack’s garden. With a nostalgic bohemian aesthetic, the capsule collection features Capri-inspired floral prints and soft colour palettes. 

Printed designs are made with Econyl®, while the lining of each piece is created entirely from recycled and sustainable fabrics, developed in-house, with all meeting Oeko Tex Standard 100.

19. Mara Hoffman

Known for her flattering, retro shapes and beloved by the fashion set, Hoffman is well and truly committed to reducing her environmental impact – and has been doing so for the last 15 years. 

While she uses Econyl® for her sustainable swimwear range, the designer has also started working Repreve into her textured pieces, a fibre made from upcycled plastic bottles that would otherwise end up in landfills or our oceans.

20. Myraswim

Myraswim is sought after for its timeless designs and versatile hues. Sleek shapes and neutral shades (black, chocolate, vanilla and clay) are a minimalist's dream come true. 

"Since I started bulk manufacturing in 2014, I frequently travelled to my manufactures overseas to always ensure my garments are being constructed in a healthy environment," says the founder, designer and owner, Bianca Anstiss

Anstiss is a pro surfer, so "having ethically made garments has been a long-term thing for me," she says. "I consider (Myraswim) 110 per cent slow fashion." However, the brand has since transformed its shopping experience into fully long-lasting with reusable, multi-purpose garment bags and environmentally friendly postage materials. 

Lastly, its national deliveries are sent with Australia Post, which is a carbon-neutral option. Its staples like the Diego top and Aloe one piece are ideal options for mixing swimwear into your daytime wardrobe. Its terrycloth Resort line is also the perfect embodiment of trying the towelling trend.

21. Stay Wild Swim 

London-based sports-luxe swimwear brand Stay Wild Swim was co-founded by Natalie Glaze and Zanna van Dijk and frames its 'buy less, buy better' approach with thoughtfully cut, block-colour one and two-piece designs made from recycled nylon

Tags and packaging are fully recyclable, the label's shipping is 100% carbon neutral, and they're currently working on the technology to recycle old swimwear into new pieces. The brand was also one of the first UK stockists for the GuppyFriend bag, designed to prevent microplastics from entering the system during washes.

22. Seven Swim

Hannah Hayes debuted Seven Swim in 2016 on a mission to achieve the highest-quality version of sustainable swimwear. Since then, her creations have been co-signed by fashion's biggest MVP's, including Kim Kardashian, who has been spotted in the Blaze bottoms. 

All of Seven Swim's solid colour bikinis are made out of an eco-friendly fabric called Amni Soul-Eco. This specific fabric naturally breaks down significantly faster than most fabrics: it takes five years instead of decades or more. It also decomposes into non-toxic, organic matter that safely goes back into the environment. 

That said, don't worry about your suit's longevity; the decomposition process only begins when the fabric is left untouched in the unique conditions of anaerobic landfills. In addition, every order is shipped in compostable mailers, and the Seven Swim factory is PETA-certified as cruelty-free and vegan. 

As an attractive bonus, all of the extra fabric scraps from production make doggy beds for shelters in Brazil. And, to make the brand even more irresistible, it's 100 per cent female-owned and female-operated. Even its factory employs an all-female staff. 

23. Fisch

Growing up in St Barths, Swedish designer Agnes Fischer has always had an affinity with the ocean. So horrified at the rapidly diminishing health of the planet's coral reefs, she pledged to create a luxury sustainable swimwear brand handmade in Italy using only fibres from regenerated fishing nets and ocean waste. 

The collection, designed to be worn from the beach to the bar, comes in bold colours and retro-inspired prints. Plus, 10% of profits are donated to the Healthy Seas project – a team of volunteer divers who recover ghost nets from the sea, which will be made into the fabric that Fisch uses.

24. Talia Collins

Riviera chic forms the mainstay of the eponymous label founded by stylist and alumni of Vogue Paris, Talia Collins. The sustainable swimwear collection – think timeless silhouettes and colourways – is aimed at “women who care about their clothes, where they come from and their afterlife”. 

The range is made using Econyl®, and 1% of each sale goes to the Healthy Seas initiative to clear our waters of marine litter. Each piece can be personalised with custom monogram embroidery to make it extra special.

25. VDM The Label

Making clothes that "look good, feel good, and do good" is VDM's motto, and they're certainly following through. Its owner and creator, Allanah Rosenwald, has always prioritised the environment, from the great outdoors to that of her factory. 

"Rosenwald works closely with our manufacturer in Indonesia, ensuring working conditions are ethical and optimal," reads VDM The Label's site. VDM's packaging is made from corn starch which is 100 per cent biodegradable. 

The brand also uses electronic invoicing, return slips, and gift cards to be as paper- and plastic-free as possible. Its solid colour suits are made of DNV GL-certified Econyl (each bikini uses roughly ten recycled plastic bottles), while its prints are made from Repreve

Repreve is also created from recycled materials like plastic bottles. Still, its composition holds patterns better, plus its production uses 45 per cent less energy, emits over 30 per cent fewer greenhouse gases and uses 20 per cent less water. 

Most of its bikini separates are reversible with equally cute linings to seal the deal, so you can truly get double the wear from a single suit. Plus, its matching cover-ups are also sustainably made out of 100 per cent eco-rayon, which is made of wood cellulose that has been grown in farmed forests certified by the Forest Stewardship Council

If you need a little summer outfit inspo, the pink paisley bikini’s matching top and skirt make for a stunning coordinating set.  

26. Duskii

Founded in October 2019 by Australian designer Patreece Botheras, this environmentally conscious collection has already had its fair share of celebrity fans, with Elle Macpherson, Karlie Kloss and Kendall Jenner all having been spotted in the sports-luxe pieces that flatter and sculpt the body. 

The high-performance activewear for the water is aimed at surfers, swimmers, divers or sun loungers who can mix-and-match swimsuits and separates that are simultaneously light, warm, supple and stretchy. The entire range is crafted from Repreve, and every purchase is sent out in 100% compostable, zero waste shipping bags.

27. Rielli

Since launching her brand in May 2019, founder Arielle Baril has been on a mission to create a sustainable swimwear line that brings out the confidence in every woman without costing the planet. 

The zero-waste label offers a capsule collection of modern designs in crinkled fabric. Each piece is made-to-order to ensure that nothing goes to waste and the small business only produces what is needed. Asymmetric one-pieces and Rio-inspired high cut styles can all be ordered to fit your measurements, guaranteeing the perfect fit every time.


Plastic pollution is one of the biggest environmental issues affecting the planet today, with an estimated 8 million tonnes of plastic reaching our oceans each year. However, there are myriad ways you can do your bit to help save our oceans, and a brilliant way to start is by changing up your buying habits.
