Looking for the best women’s ethical underwear for 2023? Read on, I’ve found over 15 sustainable and eco-friendly bra and knicker brands that might just fit the bill.

I first started writing about ethical women’s underwear, in 2013, way back in the infancy of Moral Fibres. I remember lamenting about the lack of brands, the lack of bras available that went beyond a C cup, and the lack of underwiring. Plus, I felt that bra makers seemed to think that anyone interested in ethical bras must need nothing more than two lacy triangles for support. It was a woeful picture.

Thankfully, as time has gone on, things have started to change. There is now a whole host of sustainable brands out there now catering to a range of different sizes, and offering a whole lot more support than ever before.

Whilst reading through this guide, you might want to have a look at this post on what to look for when shopping for ethical clothing. It covers topics such as what fabrics to look for and explains what all the different eco-labels mean.

Allbirds

Price: £15 – £28

Size range: XS – 3XL

Available directly from Allbirds

Allbirds, the ethical shoe retailer, has a small but perfectly formed range of women’s ethical underwear that is made responsibly from sustainable materials, and available in a wide range of colours.

Its inclusively-sized briefs, thongs, and shorts are made from a blend of sustainable Tencel and mulesing-free merino wool. This makes for a silky-smooth fit that feels barely there. The breathable materials help to wick moisture away, keep you comfortable all day, and help to minimise odour. Meanwhile, the silky-soft seams prevent irritation.

As well as knickers, Allbirds does offer a non-underwired bralette that offers everyday support.

Allbirds says that offering a carefully curated product range fit for all seasons, means that it can maintain a small, tight-knit supply chain.


Boody

All Boody garments are made from organically grown bamboo and are produced adhering to the highest standards for both the planet and its workers.

Boody is also a certified B-Corp. This means the brand has been independently verified as meeting high standards of social and environmental performance, transparency and accountability.

With inclusive sizing available on some styles, going up to 4XL, these super soft, highly functional, and unfussy designs are perfect if you’re looking for plain pattern-free women’s ethical underwear. With midi briefs, full briefs, boyleg briefs, Brazillian bikinis, hipster bikinis, G-strings, and high-cut bikinis, there is something for every preference.

A range of non-wired bras is also available – from seamless bras to sports bras and shaper bras.

Pantee is an ethical underwear brand, that launched in November 2020, with the aim of tackling textile waste in the fashion industry.

Catering for bra sizes 28A to 38F, Pantee upcycles unsold t-shirts that have been left unworn and are destined for landfill, into soft and supportive underwire-free bras and briefs.

In case you are worried about support, each bra is double-layered for extra comfort and support.

ColieCo manufactures its underwear to order and uses intelligent garment design and cutting processes. These processes help to keep textile waste to an absolute minimum.

Sizes for its soft and underwired bras range from 28B through to 38F. However, ColieCo does take requests for custom sizes if you need underwear outside that size range. I’d say that prices are very reasonable for handmade ethical women’s underwear.

Ethical clothing brand Rapanui makes its clothing and underwear in the UK (on the Isle of Wight), using natural materials, in its factory which is powered by renewable energy.

Its products are made in demand, seconds after they are ordered, so there is no waste from excess stock.

What’s even more impressive is that every product made by Rapanui is designed from the start to be sent back when it is worn out. Once your undies reach the end of their life, send them back to Rapanui. Rapanui covers the postage, and it will recover and remanufacture the material into new products. Rapanui will also reward you with a coupon that you can use to save money on your next purchase.

With vegan-friendly bralettes and knickers ethically made from organic cotton – in four different colours – they’re sure to be undies that you turn to day after day. We just wish Rapanui could introduce more inclusive sizing options.

These are all sourced from production leftovers, end-of-lines, off-cuts, deadstock, and vintage trimmings. 

To find these, the Anekdot team hunts down fabrics from factories that are closing down, makers’ surpluses, production errors, or miscalculations. This means the materials used have never been worn but make for truly zero-waste ethical underwear. 

As well as using surplus fabrics as the main material for its products, Anekdot is committed to making the absolute most of these materials.

As such, Anekdot cuts around small defects and makes its patterns in a way that minimises off-cuts. Textile scraps from its production too small to use in any of its designs also get used in other projects – from making accessories, patchworks or filling pillows.

One Essentials

Size range: XS – XL

Available directly from One Essentials

One Essentials was started in dismay at the options available when it came to shopping for ethical underwear. A cry of “How can we expect to make the world a better place if we can’t even get the f***ing basics right?” led its founder, Carrie, to want to do better.

As such One Essentials uses innovative materials to create products designed for maximum everyday comfort, but minimum impact on the planet.

Its fully traceable women’s underwear is ethically made with a blend of recycled cotton, organic cotton, and a pioneering biodegradable elastane, these super soft and stretchy knickers are ones that you’ll want to wear again and again.

A takeback scheme means that you can send your old Old Essentials pieces back for recycling, to avoid textile waste. No matter how holey, you’ll get 10% off your next condition every time you use the take-back scheme as a thank you for preventing more garments from going to landfill. Meanwhile 1% of every sale – not profits – goes towards textile cleanup initiatives.

Women’s Ethical Underwear Tips

That’s a bit of a whistle-stop tour of the women’s ethical underwear landscape in 2023. Whilst it is an improvement, there’s definitely still a long way to go in terms of underwire, inclusive sizing, and affordability.

Whilst you are here, I also have some ethical underwear tips for you! I have a guide to sustainable sports bras. I have a handy bra-fitting tip to make your bras last longer. And I have guides to underwear recycling, as well as a guide to bra recycling for charity that could be useful if you are currently updating your underwear drawer.

As well as this guide, I have guides to ethical clothing brands, ethical sleepwear, and ethical socks that you might be interested in too – also all updated for 2023.

As always, if you come across any other women’s ethical underwear makers/shops then do let me know. I also aim to update this post regularly. So do check in next time you’re in the market for underwear, from new makers/shops that I’ve found!
