It’s officially swimwear season! Lazy days sitting at the beach or by the pool are a dream if you have the right suit. Finding a well-made swimsuit that fits the way you want it to and is sustainably made can be a challenge, we know! But don’t worry, we’ve got you––and as much skin as you want––covered.

Why consider sustainable swimwear?

It can be difficult enough to find a swimsuit you feel comfortable in, and sustainability often goes by the wayside when it comes to swimsuit shopping. 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 fabrics not only create comfy, stretchy swimwear but also divert waste from oceans and landfills, promoting a circular fashion loop that’s much better for the planet. Some eco-friendly materials you might find in your swimsuit include plant-based polyamides, ECONYL®, and recycled poly. Sustainable swimwear brands also prioritize ethical and fair production practices, ensuring their supply chain is as sustainable as possible and that workers receive fair wages and safe working conditions. 

Our criteria:

We’ve rounded up the brands that hit that sweet spot between mindful production and comfy, substantial swimwear. Whether you’re looking for a more supportive bikini, a burkini, or anything in between, you’re sure to find something in the below brands’ swimsuit collections.

The brand uses 100% regenerated material like fish nets, and all of their pieces are cut and sewn at their Los Angeles factory, meaning all their suits are made ethically and are designed to last for years and years (so you don’t have to buy a new suit every season!).

And you can find plenty of trendy silhouettes, too, meaning you can keep your suit simple or opt for a cute one-shoulder or ruffled neckline.

Most importantly, they’re incredibly stretchy, designed to move with your body as it naturally fluctuates.
