Ethical and sustainable swimwear – a full guide to the best eco (& chic) brands

Dive deep – nothing says summer quite like the swimwear, and these are eco too.

As the weather gets warmer, naturally you want to spend more time outside or head to your long-awaited summer holiday. Yet, now more than ever, the idea of a staycation seems equally acceptable.

Technically, you don’t need a beach to wear beachwear. Make the most of your time outside and enjoy the British summer in the garden or balcony, even your local park. Or maybe you are lucky enough to live right next to the beautiful coastline which makes things, well, a lot more bearable.

What is eco swimwear?

Whether you prefer a two-piece, a classic swimsuit or a tankini, flattering and comfortable fit is something we all appreciate. Along with nice fabric and stylish design.

Still, most of the available bikinis and swimsuits these days are made of not so eco-friendly materials such as polyester, which is essentially plastic.

Luckily, there are brands thinking ahead of timedesigning beachwear made of recycled or innovative fabrics in a sustainable way.

So if you are looking for another way to be more conscious in your wardrobe, ethical and eco swimwear should make it to your list, especially your summer on. 

Here are the sustainable swim brands you need to know about:

How do I care for my swimwear?

To preserve its longevity, proper garment care makes all the difference. Here are a few steps that will make your swimwear look new, even when it’s not. 

  1. Wash your swimwear by hand in cold water; use natural detergent only, no fabric softeners. Don’t soak. 
  2. Rinse with clean water after use in the pool or the sea, but don’t squeeze the excess water out by twisting it, as this may break the fibres and cause your swimsuit to lose shape.
  3. Avoid drying in direct sunlight.
  4. Don’t iron your swim, just lay it flat on a drying rack in the shade.
  5. Best to avoid rough surfaces too, as they can damage your swimwear by pulling the fibres out, as well as sunscreen and oils as some products can stain your swimwear.

Bottom line

Even though most of these brands use recycled plastic materials as an alternative to the usual polyester and nylon (Natasha Tonić well done for sticking out), their practices are also ethical and sustainable which makes a big difference. So you won’t really go wrong with any of these because each contribution to an eco brand is a small step forward to the eco planet. Well done!
