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"

Cute and comfy, but didn’t last😔

Thought I loved these undies until I noticed the other day that the waistband elastic had fully gone, making them unwearable. I’ve not had them for very long, only a few months, and haven’t worn them very often in this time. I’m glad that I can now recycle them but
feel that them being branded as sustainable should mean that they last longer than the fast fashion alternatives!

Hi Eva,
I'm so sorry that you had this experience with the undies you ordered from us. That definitely shouldn't have happened and sounds like a fault with the elastic or manufacturing process. I want to reassure you that isn't standard for our items, which are usually of very high quality as well as being ethically made.
I am very happy to replace those for you, so please just let me know the details and I will get new pairs out to you as soon as possible. I hope that's ok, although please let me know if you would prefer a refund instead.
Many apologies again for the inconvenience caused. Best wishes, Sarah

Everything i have been looking for!

I cannot recommend this brand/ thong enough. They are so soft and comfy! I would say they fit true to size too :) Love.

Many thanks for your lovely review and kind words Luna. I'm really pleased that you like our undies and thanks for the useful feedback about sizing too. Thanks again for your support and best wishes, Sarah
