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.

The only pants I’ll ever wear now!

Now that I’ve realised these are the only pants that actually fit me and feel amazing on, I won’t buy from anywhere else. It’s taken me years to find my perfect knickers but I found them in the end. So happy. And supporting a great cause at the same time.

I'm so pleased that you've finally found your perfect knickers Lizzie. Added bonus that they're pants that make a difference to others too! Thank you so much for your support, Sarah

I can’t begin to explain how soft and comfortable these are! They fit really nicely and I can’t wait to purchase a multipack

Nice quality

Really nice quality pants and as the description says they fit smoothly which i find especially important under suit trousers for work. For me they come up a bit smaller than expected so i’ll order one size up from my usual size next time.
