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.

Size	Band Width (in)	Band Width (cm)	Fits Ages (Approx.)	Worn By:
Jinja	23	57-58	9-10	Hollie & Amelia, age 9 1/2, band with 23"
