Looking for sustainable swimwear? These brands make fashionable swim suits that also happen to be better for the planet.

[This post was updated on August 13, 2022.]

There’s a lot of dialogue on the internet right now around what makes consumer purchasing habits around clothing actually sustainable. Many folks are calling out content creators in the sustainable fashion niche who film huge hauls of sustainable clothing on a regular basis.

Can we really call replacing your wardrobe every few months a sustainable practice, even if you’re buying from the most eco-friendly and ethical brands? (There’s a conversation to be had around who has access to sustainable fashion brands, as these pieces are usually more expensive.)

Often, the most sustainable thing you can do is to wear the items you already have. But where does swimwear factor into this ethos?

This post is all about sustainable swimwear.

Why Buy Sustainable Swimwear 

First, swimwear simply doesn’t last as long as other sustainable clothing. If you’re doing it right, you’re exposing your swimsuit to the effects of sun, chlorine and saltwater. Over a few seasons, it’s not uncommon for swimwear to become stretched, bleached, and tattered.

As a result, you might find yourself needing to replace swimwear more often than your most cherished sustainable pieces.

If a bathing suit is going in the bin, you’ll want to make sure it is made of materials that won’t harm the planet.

In addition, swimwear is not something that you can thrift, so you have to go to the market directly if you want to find sustainable or ethically made swimwear.

For these reasons, it makes sense to prioritize and invest in eco-friendly swimwear from sustainable brands.
