The Best British-based Sustainable Swimwear Brands

Now we’re out of complete lockdown, our lifestyles and leisurely activities can be a little more enthralling than what was once a day of Netflix binging or a procrastination-fuelled day of working from home. We can enjoy things like beach days or swimming pool trips, maybe even set foot abroad this season.

I haven’t purchased new swimwear in going on five years. My trusty black, strappy bikini has served me well time and time again. This year, I decided I wanted to invest in some new swimwear. I wanted something a little more exciting, something more me, and hopefully, something confidence-inspiring to wear to my local beach.

I decided to buy new, but I wanted my purchase to be as sustainable as it could be within my budget. I set out to find what sustainable swimwear options there are on the market and thought I’d share my finds.

High Street

If you’re a high street gal, the largest selection of sustainable swimwear I found was on Asos. Asos have a dedicated page of swimwear made from recycled plastic and textile waste. Highlighting three brands: Monki, Asos design, and Weekday means that there are hundreds of swimsuits to browse through and lots of choices, ensuring the purchase you’re making is the right one! I decided to search these brands website individually and discovered a swimsuit I adored from Monki. I came across a nineties inspired, high legged red swimming costume, made from a recycled polyester blend; I knew this would be a timeless piece for me.

Inspired by the devastation climate change is causing and the destruction of our beaches across the globe, London based swimwear brand, Paper, was created. The brand uses ECONYL for their swimsuits, a 100% regenerated Nylon fibre made from recycled fishing nets and waste products found in the ocean. In combination with this, they use REPREVE yarn, made from old plastic bottles which use less energy and water than alternative fibres.

Paper’s website provides tips on how their customers can sustainably care for their garment post-purchase and a thorough explanation of how their swimwear has a greater impact on our oceans. Their swimwear has built-in sun protection, and when it does reach the end of its lifespan, you can send it back to the brand to be recycled and receive a discount off your next purchase.
