15 Sustainable Swimwear Brands You Need To Know About

Shop my edit of 15 responsible swimwear brands that put sustainability first

The UK government has announced that we are able to travel abroad for non-essential trips, and upon returning back in the UK will be exempt from the usual 2 weeks in quarantine (depending on the country). My family and I had convinced ourselves that we wouldn't be able to go on our summer holiday this year, and thanks to the latest news it is all going ahead.

Shopping for swimwear is my favourite pre-holiday activity, where I normally tend to treat myself to a bikini or swimsuit. This generally acts as the central point of all my excitement leading up to the holiday, which I will go on to wear all summer long, and every summer after. Having had plenty of time in lockdown to think about my shopping habits, this year I want to invest in something that is sustainable.

Most swimwear on the market is sadly made from synthetic fibres that make nylon and polyester, which need tons of water and produce lots of nitros oxide. With nine out of ten items ending up in landfills, it is clear that we need to shop better and make careful decisions with how we consume.

Thanks to the recent surge in designers and consumers voicing their concerns about fast-fashions impact on the environment, there has been a growth in brands producing swimwear made from sustainable material - the most popular being ECONYL® - a 100% regenerated Nylon fibre made from recycled fishing nets and any waste products found floating around the ocean. Did you know that Ghost nets are responsible for entangling millions of marine animals a year? So by removing them from the ocean and turning them into something functional we are helping to clean up the oceans.

Frankies Bikini

Founded in 2012, Frankies Bikinis has recently launched a sustainable range using fabric that is produced using Amni Soul Eco, the only eco-friendly polyamide yarn in the world. This innovative technology allows clothing to quickly decompose after being properly disposed of in landfills. Unlike other fibres that take decades to be decomposed, Amni Soul Eco takes approximately three years to be eliminated from the planet. I think it is safe to say, we shouldn't be throwing any clothing into landfill, however, Frankies Bikini offers a solution to the problem if this scenario does arise.


Belize's motto is "that loved clothes should last", with attention being heavily weighed on the ability to care for each item, and how this will help avoid colour fading, shrinkage and misshaping. By changing your washing habits to hand-washing, you are instantly opting for an ecologically friendly approach, which will help extend the life of your garment. Belize uses the very best Italian crepes, cottons and swim fabrics, hand woven Indian cloths and English printers to give each garment credibility and longevity. Belize collaborates with small, specialised factories and craftspeople to develop, grow and learn together. Check out Belize's sustainability page to discover how you can incorporate their care habits into your own washing, drying and storing routine.
