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.


Person wearing a t-shirt and Allbirds tencel knickers.

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.

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.

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.

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.

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.

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.

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!

  1. Thank you for compiling this list, as whilst I ship almost solely in charity shops for my clothes I’ve still been buying my socks pants and bras from normal fast fashion shops.
    Disheartening about the lack of sizing but hopefully we’ll get there soon!

  2. I see many of your comments are about affordability. I believe i have the answer. During the next 6 months i am putting together a new brand using ethically manufactured sustainable yarns. I will be bale to sell on line the majority of style of Knickers for £5 and Bras from £8. These will be made from 95% bamboo yarn and 5% elastane.
    I am designing everyday wear that has a sustainable yarn that also helps to keep the skin moisturised, this will help eczema and other skin conditions. Unfortunately this will be higher in price, BUT i believe i should be able to market these for Knickers at £12 and Bras around £17. To achieve this i need help in getting it out to market without stupid marketing costs. anyway could you put it out there if any of your readers would consider buying at these type of costs. Many Thanks

  3. Thanks so much for this! I have really been struggling to find ethical and eco-friendly underwear made in the UK (now that we’ve left the EU the import taxes are so high!). This has been such a helpful list! Thank you so much! xx

  4. Encouraging to see that sustainability is at last making its mark on the lingerie industry and, hopefully, if you update this article in two or three year’s time it will have twice the scope. Fingers crossed. In the meantime could I mention true vintage lingerie (as opposed to modern-made ‘retro’ undies)? Surely true lingerie sustainability is reuse? Why make something twice? Vintage lingerie need not involve images of “used” or “old clothes”. Far from it. Fabulously chic ‘deadstock’ lingerie (unworn, labels attached) is readily available. Elizabeth Cline sums it all up so well here:

    “Resale offers the wardrobe-rotating fun of fast fashion without the guilt or waste. By driving preferences away from disposable fashion towards higher-quality clothes, reuse is a boon for our personal style and the planet.” – Elizabeth L. Cline, Author of The Conscious Closet.

  5. Very nice list but it’s truly dispairing that all these brands make bras for either very small sizes only, or up to a 36 size but no wires or no padding. There’s nothing more horrible than wanting to make the right choice and not being allowed to.

    Not even talking about affordability here. Just the simple fact of all these “ethical” brands repeating the horrendous discourse that some bodies are adequate and some are wrong.


    1. I agree Anna, the lack of inclusive sizing is a problem across the whole ethical fashion sphere – not just the ethical underwear area. I think it’s a problem in fast fashion too, but seems more pronounced in ethical fashion because as you say it’s simply not possible to make an ethical choice even though you want to.

  6. Hi!
    This is a really good list, although I have the same problem as others in that there’s no way I could afford most of those prices. They’re the right prices for sustainably, small-scale-produced items…and that’s the problem with the fashion industry!
    Anyway, I wondered if you’d come across a great brand called Pip and Pantalaimon? I don’t know a huge amount about their sustainability, but they’re definitely produced in the UK with surplus fabrics and they only make to order. They are probably best suit those who like vintage style, but they’ve got some more mainstream styles too. I’ve got 3 of their less expensive girdles and they’re fabulous.

  7. Hi, I love your blog and have learnt a lot since finding it. I don’t think that silk can be considered ‘ethical’ though

  8. Lara intimates are really good too – they cater for all sizes and will make custom made bras too. They’re all made to order in London.

  9. Still nothing affordable in my bra size. There’s one that’s £90, but I don’t have that kind of money. I also want padding, underwiring and something that looks sexy. Nothing like that available from any of the companies listed.

  10. La Fille D’O is a wonderful Belgian brand that is perfectly ethical: everything is produced in Belgium and special attention goes to non-damaging chemicals for dyes etc. They have with or without wire and they are famous for the original design of the monowire. I have a bra from them and it’s my favourite one, been wearing it for half a year and if I could I wouldn’t wear anything else….

    1. Have a look at whatlydiamade.com Inclusive sizing (including custom orders), very body positive. designed and handmade in Glasgow. I’m not 100% sure what materials are used though!

  11. We have a brilliant underwear company in Perth called molke everthing is designed produced and created here in Perth .It started as a breastfeeding bra company but everybody wears them now ..check out their fb page and their websìte

  12. There’s a lovely French brand called Do You Green – ethical materials in simple but still pretty designs with a couple of underwired bras. The focus is on materials and they use bamboo etc. I’ve not bought anything but have my eye on a couple of pieces.

  13. Great article. I would also encourage you to look at Molke – particularly for the larger busted and those breast feeding who don’t want underwiring. Made in Perthshire!

  14. I don’t know that any company going only up to an E cup could be catering for curvier ladies, given that most people are wearing cup sizes that are way too small for them…but I would love to see more ethical retailers doing custom orders!
    I’m way outside of the norm in terms of cup size, so my expectations are pretty much rock bottom. :) But I would pay 3x average off-the-rack large cup size prices for a bra that I knew fit me and was made using ethical environmental and labour practices!

  15. Yes this is super useful! I must admit undies are still one of the things I buy from mostly not so ethical companies due to not finding ones that are comfy, supportivde, good value, good value for money and not made for the yoga like forest nymphs you speak of (not that I have anything against them, that’s just not me) so I will definitely be checking some of these brands out!
