Size Guide

View our sizing charts below. If you're in-between sizes, we recommend sizing up for comfort! If you need more specific sizing help, please email us at help@youunderwear.com.

 

How to Measure Yourself

Band: wrap the tape measure around your body, just under your bust.

Waist: measure around your body approximately 5cm below your natural waist where the waistband of trousers normally sit.

Lower hip: wrap the tape measure around the fullest part of your hips and bottom.

Girls' Bralettes:

We feel that there isn’t a set size for bodies at different ages, and we don’t want to put any additional pressure on young girls, so our sizing looks a little different. We have 4 sizes, all named after Ugandan towns! We suggest using band width as a starting point, although do get in touch if you have any specific sizing questions.

How Long Will Delivery Take?

We aim to send out all orders placed before 2pm the same day and you’ll get an email to let you know when your order is on the way! 

 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.
