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.

comfortably and secretly being reminded to make a difference

I love these trunks. They are incredible comfortable... and the best is the secret reminder to make a difference. Wearing these is like wearing a superhero outfit that no-one can see.

Fantastic all-round comfort and quality.

Fantastic. Most comfortable pants I’ve ever bought. Will definitely be buying some more as other M&S ones wear out! Very soft when you wash them too.
