What size am I?

Details of the styles and sizes available for men and women are given below. If you aren't sure or are in the middle of range, we would suggest you go for the larger size so they are more comfortable.
Our bikinis in particular tend to come up a bit small, so we would recommend you going one to two sizes larger than you usually would to ensure a comfy fit.

To measure yourself:
Band: wrap the tape measure around, just under your bust.
Waist: wrap the tape measure around the narrowest part of your torso.
Lower hip: wrap the tape measure around the fullest part of your hips and buttocks.

If you need more specific sizing help, please email us at info@youunderwear.com.

What if I change my mind? Refunds & Returns

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.

Provided they are unworn, unwashed, undamaged and in their original packaging, we will happily exchange the items for another size, style or colour, or refund you if you are not completely happy with your purchase.

We hope this gives you confidence to refresh your underwear drawer and start changing the world one pair of pants at a time.

If you have any further questions though, please don’t hesitate to contact us at info@youunderwear.com.


Packaging

We believe in minimising the packaging and plastic that we use, so all Y.O.U underwear is packaged in resuable, 100% organic cotton bags. These are perfect for storing your undies while travelling, or for holding jewellery, power cables or other items you need to keep safe. We want you to reuse them and not just throw them away, so you can always use them as a gift for someone who makes a difference if you don't want them yourself!


To keep our undies safe on their way to you, we use small recycled plastic outer bags. These are already recycled and can be recycled again in most areas (this does depend on your local Council collection facilities). We are hoping to move to paper or compostable packaging next year and are currently looking into the best options based on our order volumes and delivery locations.

We appreciate that many people care about packaging options and we are working to cut out all our single-use plastic and make our packaging as sustainable as possible. We also offer discounts if you don't want our reusable cotton bags (or already have one), so please just get in touch at info@youunderwear.com and we will arrange that for you.
