Ethical underwear UK: the best underwear, lingerie and sleepwear brands laid bare

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 your smalls can make a big difference – and choosing ethical underwear has a surprisingly big impact on everything from the planet to the people who make it.

We believe that just because something is sustainable doesn’t mean it can’t look good.

Below are seven 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.

Pantee black underwear set

The pain of a long day of wearing an underwired bra with tight straps is all too familiar… But when it comes to Pantee underwear, comfort is key: we’re talking no underwires and no tight straps. 

Choose from their selection of thongs, boxers, bikini or high-waisted briefs and double-layered, underwire-free bras – all of which can be mixed and matched so you can find your perfect pairing.

Pantee makes its underwear from upcycled deadstock fabrics. Since launching in November 2021, they have upcycled over 1,500kg of deadstock materials into bras and knickers. 

The items are cut and sewn in a small sample room in Bangladesh. Its workers are guaranteed safe working conditions, paid above average living wage and earn bi-yearly bonuses. 

Pantee is also a 1% For The Planet member, which means it has committed to giving one per cent of gross annual sales to certified non-profit organisations.

Ethical underwear | Yellow cotton underwear from Rapanui

Rapanui’s underwear is as simple as it comes. But that’s not a bad thing, because with pants this well made, nothing else really matters. Available, individually or in bundles, in a range of saccharine hues like mint and lavender, the knickers are super soft and comfy where it counts. Plus they have wide elastic at the waistband for a sleeker, more flattering fit.

Based on the Isle of Wight, Rapanui makes all of its items in the UK using organic materials and in a factory powered by renewable energy. The company’s factory manufactures orders in real time when the item gets sold, so there’s no waste.

Worn-out items can be sent back and get recycled into new products – something that’s only possible with the purest materials.

Rapanui is a brand that understands the bigger picture. So, it shares its supply chain and its technology with everyone. This means anyone can use that information to start their own brand. Now that’s what we call selfless.
