Best women’s sustainable activewear UK: plastic-free workout clothes and sportswear
Underwear, knickers, pants, lingerie, briefs: no matter what you call it, it’s very likely you wear it – and if you don’t, well, you do you. You’re fabulous. But, our smalls can make a big difference – and choosing ethical underwear has a surprisingly big impact on everything from personal comfort, to the planet and the people who make it.
We know that sustainable underwear feels great. Did you know it can’t look great, too?
Below are twelve brands who prioritise beautiful design and comfort alongside ethics, whether they choose to work with only surplus fabrics, source organic materials, or partner with charitable organisations that empower vulnerable women.
You might prefer sexy silks, or you might be more of a super-soft cotton gal – but whichever you’re after, we’ve got both cheeks covered.
The Live Frankly seal of approval:
Those featured here are really good brands, doing good things. To be included in this list, each brand has been given the Live Frankly seal of approval. We are not a certification, but we talk with every brand and ask them to complete a comprehensive questionnaire about their ethical standards before we feature them. No brand is perfect – we’re all operating in an imperfect world – but only purpose-driven brands that are working to change things for the better will be featured on Live Frankly.
We ask that workers’ rights and pay are ensured across the supply chain, that brands use sustainable materials and want to know about their governance structures. This means you can be confident these brands are some of the most ethical and sustainable around. If you have any questions please get in touch.
