Shopping for swimwear can feel daunting and, frankly, a bit uncomfortable. From terrible dressing room lighting to trying to find a style we feel confident in…the process leaves a lot to be desired. Add to that the fact that many swimsuits are made from unsustainable materials or with concerning ethics and manufacturing practices. Oof.

Thankfully, there are sustainable swimwear brands out there creating cute and comfortable swimsuits for all shapes and sizes of bodies. Eco-friendly materials derived from recycled plastics not only create comfy, stretchy swimwear but also divert waste from the oceans, promoting a circular fashion loop that’s much better for the planet. These brands prioritize sustainability and ethical manufacturing, and they make shopping online easy and, dare we say, fun. Many of the below brands also include unedited photos, real customer reviews, and wonderful support teams to help you find the perfect style and fit. From mix and match bikinis to one-pieces and bodysuits, you’re sure to find something for your next pool day. 🏖️

With spring 2023 starting up, be sure to snag natural sunscreens, face sunscreens, eco-friendly sunglasses, and eco-friendly sandals, too!

Oh, and they’re affordable, too—most less than $100. We especially love Summersalt’s unique one-pieces—they provide comfortable coverage and fit while still feeling sexy.

Wolven’s founder Kiran Jade draws from her South Asian family’s background for its gorgeous patterns and textiles. Wolven’s swimwear for example—made up of one-pieces and bikini sets—includes mandalas and henna-inspired designs. Each piece is made from 80+ percent recycled plastic bottles with a bit of spandex for extra stretch, so you can run freely across the shores or cannonball into the pool. The fact that many of Wolven’s suits are reversible is so fun to experiment with. (But heads up: If you need structured support, cups, or additional lining, this might not be the brand for you!) Wolven orders are carbon-neutral, give back to environmental causes, and are sent in either recycled or biodegradable packaging.

| Certified B Corp, Fair Trade Certified collections, recycled polyester, gives back
Price Range | Separates starting at $59, one-pieces starting at $129

If you’re looking to break from the itty-bitty bikini mold, the certified B Corp makes gender-neutral tanks, halter tops, and racerbacks that can be paired with shorts of varying lengths—or you can opt for a unisuit altogether. All are quick-drying, equipped with UPF sun protection, and made with OEKO-TEX certified fabrics. (And the brand’s ethics and sustainability are top-notch, too.)

The bandeaus in particular can be worn a number of ways, wrapped around the neck for extra support or tied into a front knot. Sizes go up to 40H for cups and 43.5” for bottoms.

We love this brand’s diverse swimwear options, like tankinis, mommy-and-me sets, and swim dresses!

| Locally & ethically made in England, European-sourced nylon, Certified Plastic Negative, biodegradable packaging
Price Range | $139
Size Range | US 2–14, UK/AUS 6–18

Seven sizes in one? We know, but hear us out! Youswim simply doesn’t do sizes; the brand has four uniquely simple styles instead—the Aplomb, Eva, Poise, and Verve. Find the fit you love most, choose one of the vibrant colors, and pay one price across all pieces. Each sustainable swimsuit is made with European-sourced nylon and woven ethically in England; the team is also diligently working on a recycled nylon fabric to use instead to maximize its sustainability.

Hackwith Design House has been a longtime favorite of The Good Trade because of its stunning wardrobe staples and the handmade-to-order quality. The swimwear line, HDH Swim, features more of the brand’s classic and timeless designs. With stunning color palettes and inclusive, well-fitting suits, a piece from this thoughtful swimwear collection is a summer essential.

14. Galamaar

Best For | Recycled nylon and retro prints
| Made in LA from recycled Econyl®, recycled hang tags, regenerated mixed metal hardware, eco-packaging materials
Price Range | Separates starting at $118, one-pieces starting at $248
Size Range | XS–XL

At Galamaar, waste-to-wear is the name of the game. These beautiful suits are made in part using recycled Econyl®, a fabric derived of nylon from trashed fishing nets that account for nearly 10% of ocean pollution. Not only is the material sustainable, but it’s also made to last: following the brand’s care guidelines, your Galamaar suits can last a lifetime. Made in a small, family owned and operated fair-wage manufacturer in LA, you can feel good about this swimwear that is ethically made, eco-friendly, and extremely chic.

15. Londre

Best For | Minimalist swimsuits with a twist
| Recycled plastic bottles, recycled water use, OEKO-TEX certified production, biodegradable packaging, size-inclusive
Price Range | Separates starting at $69, one-pieces starting at $99
Size Range | XS–5XL

Londre was born when its co-founders became obsessed with creating the highest quality bodywear with the lowest impact. Now, the brand’s best-selling one-pieces can be worn to the beach as easily as they can be paired with a blazer. But if you’re looking for something more classic (with a twist!), opt for the high-waisted bottoms and asymmetrical tops. We’ve never worn a suit quite like one from Londre—the cut and shape are so unique and we get lots of compliments on these pieces. The New Classic bikini top can be a little confusing to put on (there’s no pesky tags!), but the plunge neckline, thick support band, and stunning ruching are worth a little trial and error. Made in bright colors and patterns, the products are able to withstand all salt, sand, or sweat.
