About Our Underwear

Do you have a bralette for larger cup sizes?

We do! Launched in Autumn 2022, this product was a direct result of customer feedback. Our supportive bras offer more support and coverage but still with our signature super-soft organic cotton - all without wires!  The bra comes in 3 band sizes, each of which is available with a standard cup size and a + cup size, providing greater flexibility to suit different body shapes. 

What dyes do you use in your underwear?

All of our underwear is dyed with low-impact, fibre-reactive dyes that are safe and GOTS certified. They contain no heavy metals or other known toxic substances and meet all EU criteria for eco-friendly garments.

How do I know what size I am?

We have an easy to use size guide for all our underwear, which you can find here. We hope that makes it simple! If you're in between sizes, we recommend sizing up for comfort. If you need any specific sizing advice, use the chat function to send us a message and we'll get back to you as soon as we can. 

Can I get a refund, or exchange my underwear?

We want you to love your new super soft Y.O.U undies and hope that they fit perfectly. However we understand that isn’t always the case, so we offer a happiness guaranteed return policy. 
If you are unhappy for any reason, we offer a fuss-free exchange or refund on all items within 30 days of purchase. Simply return them to us at the address below, along with your name and order number: Y.O.U underwear, 11 Bodley Place, Oxford, OX2 7TF. If you'd like to organise an exchange, let us know your details and what size is best at
Unfortunately, as a small business we can’t cover the cost of returning the items to us. However we do pay for your replacement undies to go out.

Can I use Y.O.U underwear as swimwear?

Our organic cotton undies can be worn in the sea, lakes, rivers and any other natural bodies of water. We recommend avoiding chlorinated pools or exposure to chemicals as this may damage the dye and fabric. Make sure to wash well after every use! Our team has used them when swimming outdoors and they are super comfy, retain their shape and don't come off when jumping in! If you're worried about them being see- through, our bralettes are double-lined ensuring ample coverage.

I'd like to stock Y.O.U underwear!

If you're interested in stocking Y.O.U underwear, please get in touch by emailing 

 What shall I do with my old Y.O.U Underwear?

We're glad you asked! We recently introduced a recycling programme, using TerraCycle. You can send us your old underwear, sock and tights (any brand!) and we'll make sure they get recycled. Find out more about how to recycle here. 

Will my underwear stretch?

Yes - it will mould perfectly to your body during the day! But don’t worry, it won’t lose its shape over time – it will always spring back.

Will my underwear shrink? 

No, it shouldn't. All our underwear is made from pre-shrunk fabric, meaning it won’t shrink in the wash, even at higher temperatures. We’ve even had reports of zero shrinkage at (accidental) washing temperatures of 90 degrees! 

How should I wash my underwear?

  • We recommend washing all clothes in a cool wash (30 degrees), but if you’re worried about hygiene, it’s best to wash underwear at 60 degrees to kill germs (along with household linen and towels). 
  • Turn your undies inside-out when washing. 
  • Wash your bralette less often – once a week is enough!
  • Hand dry for a smooth, crinkle-free finish (in case you’re the sort to iron your undies!)
  • Add half a cup of white vinegar to your laundry loads to remove pesky stains, add brightness to whites and neutralise odours.

Where can I buy Y.O.U Underwear? 

You can visit our shop in Oxford's Covered Market! We're also stocked in Living Fibres in New Zealand, and Indigo in Oxford. We also do various markets throughout the year.


What is your underwear made from?

Our underwear is mostly composed of GOTS Certified and Fairtrade Organic Cotton. 
In order to ensure the best fit, we’ve combined our organic cotton with 5% elastane - otherwise, our underwear would easily lose its shape. We admit that we’re not perfect in this respect, but are proud to be 95% of the way there when it comes to our materials. We’re working to incorporate more sustainable alternatives and our recycling scheme makes sure that our underwear doesn't end up in landfill. 

Where is your underwear made? 

We work with India’s leading sustainable and ethical manufacturer.

We know that the growers, spinners and makers who produce our underwear are paid and treated fairly. In 2019 we even visited the factory for ourselves and met the people who make our underwear! Learn more about our factory and manufacturing processes here. 

You're a B Corp - what does that mean? 

We wanted to become a B Corp to show that purpose, people and planet mean more to us than profit. With giving back and sustainability at the heart of what we do, we're so pleased to have our work backed up by something as respected as a B Corp Certification. It's a rigourous process that took almost a year, but we came out with a score over double the necessary to qualify, and as the highest-scoring B Corp in the UK - and top fashion brand globally! You can read more about our B Corp Journey here. 

Why do you plant trees with Ecologi?

We want to reduce our carbon footprint and environmental impact as much as possible, and we think that planting trees is a great way to help the earth! For every sign up to our weekly email newsletter, we plant a tree with Ecologi. They work with Eden Reforestation to plant trees ethically and sustainably, and have transparent data backing up their claims. Sign up to our newsletter here to plant a tree for free. 

What packaging do you use?

Every order is packaged in reusable,100% organic cotton bags, then parcelled in a biodegradable mailer made from 100% recycled materials.

To further our zero-waste commitments, we’ve partnered with YagoEco to turn our mailing bags into beautiful green recycled plastic earrings! If you’d like to ensure your packaging gets reused, feel free to send any old mailer bags back to us at Y.O.U underwear, 11 Bodley Place, Oxford, OX2 7TF. 

We also offer a £1 discount if you don't want our reusable cotton bags (or already have one), please use the code NOBAG at checkout.

Our Donations + Giving Back

How does your buy-one-give-one system work?

For every pair of Y.O.U Underwear from our core collection you buy, we donate one pair of underwear to the charity Smalls for All. They work closely with partners at home and abroad to ensure that underwear reaches the right people, in a sustainable and culturally conscious manner. We don’t usually donate our own underwear, instead supporting the local markets. 


Who are Future Dreams, and how do you support them?

Future Dreams is dedicated to raising funds for support, awareness and research for those touched by breast cancer. A cause close to our hearts, we're delighted to be able to support the charity with a £1 donation for every pair of underwear sold from our light pink range


How does the Mara Collection give back?

Our collaboration with KikoRomeo is inspired by traditional beadwork carried out by Maasai women in Kenya. Every purchase from our Mara Collection will provide a pair of underwear to girls in the Maasai communities of rigorous and Olorgesailie, as well as supporting the work of the Ajuma Foundation in Kenya.


How can I support Smalls for All directly?

There are a number of ways you can support Smalls for All: 

  1. Donate at checkout: We collect direct donations at checkout - even £3 will make a massive difference! or donate via Smalls For All's website here. 
  2. Donate gently-worn bras and new pants: send them directly to Smalls for All’s warehouse (Five Sisters Business Park, Westwood, West Calder EH55 8PN). 
  3. Volunteer! Smalls for All have a warehouse full of underwear that needs sorting! If you live near Edinburgh, and have some time on your hands, why not give them a helping hand? 

Can I send used underwear to Smalls for All?

Smalls for All accepts gently-worn bras that are clean, and brand-new underwear with labels attached. They don’t accept used underwear. If you'd like to recycle your old underwear, you can send it back to us to be recycled by TerraCycle. You can learn more here.
