What Is Sustainable Swimwear? Eco friendly or ethical bathing suit would be made of either organic cotton or recycled polyester so they don't contain any harmful chemicals that could contaminate water sources.

Ethical clothing companies consider their environmental impact alongside their worker's rights and animal welfare. Luckily for us, there are some amazing eco-friendly swimsuit brands out there making it easy!

A swimsuit is one of the most important pieces of clothing that any person wears. Not only does it cover up your private areas, but it protects you from harmful sun rays and chlorine.

 Unfortunately, many people don't know this and wear cheaply made suits that will never last them more than a season without becoming too faded or worn out to use again. That's why we created our sustainable swimwear line! 

The eco-friendly swimsuits are made with high-quality materials, so they won't fade or break down after just one summer in the water! 

There are also different styles for everyone's tastes - bikinis, tankinis, halters, name it! So to find your perfect suit today and make a difference by choosing an ethical option.

Let's get started!

Some Info About Fabrics

The two most popular kinds of fabrics used to make swimsuits are polyester and nylon – both of which happen to be plastic. Do you remember about microfibers? It talks all about the problem with plastic fibres.

So, does that mean you can never wear a swimsuit again? Of course not, it’d be silly to avoid swimsuits simply because they’re made from plastic, but that doesn’t mean you can’t make smarter choices.

I like to make more eco-friendly choices when it comes to swimwear by opting for ethical manufacturing where the workers are paid a fair wage, recycled and sustainable materials, and of course, a range of fun colours and shapes.

So, here are some sustainable and ethical swimwear brands you're going to love and a few things you should be looking for when shopping. Obviously, wearing the swimsuits you already have is always the best option.

If you’re looking for a little refresh, you could always mix and match with your existing pieces or pick up a scarf or hat secondhand to complete the look.

1. Eco-Friendly Fabrics

As I mentioned prior, most swimwear is made from virgin polyester or nylon. Unfortunately, this kind of material not only sheds micro-plastics into the water with each wash, but it's also a waste of resources.

Thankfully, there are several innovative, sustainable swim fabrics out there.

One of the best eco-friendly materials is ECONYL – it’s regenerated nylon from pre and post-consumer products. 

To make ECONYL, waste like fishing nets, fabric scraps and carpet flooring is used in a regeneration and purification process.

Then, the nylon is processed and turned into new swimwear products.

There are other types of recycled swimwear fabrics, such as REPREVE, which is made from recycled plastic bottles.

Yet another material is EcoLux, which is just another term for recycled nylon fibres. 

If you're truly hoping to avoid plastic at all costs, you could invest in a yarn bathing suit or a biodegradable one made from Merino wool.

2. Quality Products

As a general rule of thumb, you want to avoid brands pumping out new swimsuit collections almost every week.

Most sustainable and ethical swimwear brands will limit the collections they release each year to ensure the quality of their pieces. Not to mention, fewer collections also means fewer materials and resources needed to make the swimwear, keeping it sustainable.

When a brand isn’t constantly releasing new collections, it means they can pay more attention to detail and develop durable pieces that will last you more than just one summer.

Fewer collections released also mean natural resources aren't being overused. However, even if the products are made from recycled content, it still takes a lot of energy and resources to make.

Slow fashion is much better for the planet and doesn’t encourage overconsumption.

3. Ethical Production

It’s important to question how your swimwear is made, just like you would your shirt or your shoes. Is it contributing to harmful environmental practices and the mistreatment of factory workers?

You want to support brands that don’t harm the environment as the item is being crafted. Better yet, you want to make sure the people making the items aren’t being exploited or paid pennies.

It’s important to look for transparent brands that ensure their garments are made ethically. Ideally, swimwear production should be energy efficient, value water, be produced locally, and support ethical working conditions.

Tips for Every Body Type

Prepare to be a beach bombshell: From tummy-trimming wonders to lift-em-up champs, these genius style tricks and super flattering suits will turn even the most swimsuit-wary gal into a certified sun goddess.

1. If You Want To Slim The Hips…

Don't go wild on the bottom

The less going on there, well—the less going on there!

Do bring the focus up

with a top in a lighter colour, or with fun details or a pretty pattern.

Do go for a fairly high-cut bottom

to create the illusion of longer, leaner legs.

The best swimsuits for pear shapes

Nautica Swim, sizes 6-16, $102,

Boden, sizes 0-18, $74,

2. If You Want To Boost A Small Bust…

Don't rule out an underwire

"It gives shape to small busts," says Suze Yalof Schwartz.

Do go for extras

like ruffles, beading and pleating. They add bulk and visual interest.

Don't do bandeau

"They'll flatten you out even more," says Suze Yalof Schwartz.

The best swimsuits for small busts

Sandy Bottoms by Red Carter, sizes XS-L, $135,

Banana Republic, sizes XS-XL, $110,

3. If you want some belly control…

Don't go for shine

It highlights every lump and bump. Matte is much better.

Do skip tankinis

unless you find one with an un-clingy top, like the striped style above.

Do show some skin

A high-cut leg or low-cut top draws eyes away from your middle.

The best tummy-trimming swimsuits

J.Crew, sizes 2-14, $125,

Old Navy, sizes XS-XXL, $30, Old Navy stores

4. If You Want To Support A Big Bust…

Do nix triangle tops

if you're bigger than a D-cup—not enough support.

Don't do high necklines

unless you want a uni-boob. Didn't think so.

Do you know that underwire or a hidden bra

is a must if your top's not a halter.

The best swimsuits for big busts

Malia Mills, sizes 2-16 A-D, $325,

Tommy Bahama, top sizes 34B-38DD, bottom sizes XS-L, $130,

5. If you want to flatter your curves…

Don't run from stripes

Just be sure they're vertical or angled across your body.

Don't say no to bikinis

Just avoid thin string ties, which can dig and create bulges.

Do try a wrap style

if you have a thick middle—it's a waist whittler!

The best swimsuits for plus sizes

Lands' End, sizes 6-18, 16W-26W, 4-18 short torso, $107,

Shape Fx, sizes 4-18, 14W-24W, $39,
