9 Sustainable Swimwear Brands We’re So Glad We Discovered

Our swimdrobes have been transformed.

Last Updated on May 17, 2023

Is there anything better than lying on the beach in swimwear? Yes — lying on a beach in sustainable swimwear.

As we’ve grown more aware of the damage fashion is doing to our environment, it’s become harder and harder to ignore. Countless sustainable brands are popping up, while many high-street stores are working on becoming more eco-friendly too by using sustainably made materials and keeping a closer eye on their supply chains.

So it’s unsurprising that the market for conscious swimwear is rising. According to Lyst, consumers are now looking for eco-friendly swimsuits more than ever before, with searches for sustainability-related keywords increasing 101% over the month of May this year. The word ‘recycled’ relating to swimwear also saw an increase in searches by 211%.

However, it’s not always easy to separate those that are truly kind to our environment through the use of eco-friendly and recycled materials from those that are simply greenwashing customers. And to be honest, since these are all still quite new concepts, they can be a bit confusing. That’s where we come in.

We’ve made it our mission not only to find pieces that will help you feel confident at the beach but those that do so with the added bonus of helping the planet too.

So without further ado, here are some of our favourite sustainable swimwear brands to get to know now.


Peony Swimwear

On a mission to create swimwear that are as sustainable as they are beautiful, Peony make all of their luxurious swim/resortwear using recycled materials – no exceptions.

To add to their sustainability credentials, Peony’s factories are Social Accountability International – SA8000 certified and as a company they are Carbon-Neutral certified.

Make a statement with your swimwear while helping to clean waste from the ocean — that’s Fisch’s mission.

HUnza G Red Juno BIkini

Hunza G’s take on sustainability is a bit different from others (but as effective nonetheless). 

In order to counter overproduction, which can lead to more textile waste — something that fast-fashion brands are known for — Hunza G has a one-size stance (one size for all items, so there are no chances of some sizes selling poorer than others and eventually getting wasted).
