The 17 Sexiest, Sustainable Bathing Suit Brands

Here’s the think about shopping for sustainable bathing suits: no, you can’t get ones made without petrochemical-based synthetics. I’m sorry.

I know you’ve seen some crocheted bikinis made with cotton, but unfortunately, once that crochet cotton gets wet, it stretches out. Believe me. I had one, and when I complained to the brand, their answer was that it’s not supposed to get wet. Oh! OK. It’s just decorative, then?

So, the what is a conscious consumer to do?

First, look for bathing suits made with recycled fabric, either from fishing nets or plastic water bottles. Then, look at where the textile is printed, and where the bathing suit is sewn. You want to make sure it’s made ethically in a country with strong manufacturing protections.

Lucky for you, there’s plenty to choose from with that criteria!


The sexy sustainable fashion brand from LA now has a swim collection as well, made from recycled polyester.

Hirsuit by Otherwild

Hirsuit Swim by Otherwild is an androgynous swimsuit designed for a wide variety of bodies and gender expressions.

Chitosante is made out of crushed shells (a byproduct of the shellfish industry) and is used for its anti bacterial and odor resistant properties. Plus, it provides that smooth, controlled fit that you’d get from synthetics but is better for you and the ocean!

And don’t forget your Guppyfriend

Many of these brands are using recycled plastic to make their swimwear, which is amazing because it means less virgin plastic being introduced into the world. However, it doesn’t keep microplastics from gradually breaking off and getting into our waterways. Washing your bathing suit (or any of your synthetic clothing) in a Guppyfriend filter bag helps to decrease the amount of microplastic shedding from your suit polluting the water.
