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"
Kira	25	63-64	10-11	Help us fill this in ...
Lira	27	68-69	11-14	Liv, age 11. Phoebe & Flora, age 11 1/2. Lana, age 13 1/2, 69cm band width, wears 30B/XS. Beth, age 14.
Masaka	29	73-74	13+	Hannah, 32C

Masaka	27.5-28.5”	37.5-38.5”	13+	10 (EU 38)

Pyjama bottoms:

Our PJs are designed to be unisex, so the sizing is a bit more flexible with an elasticated waist, cord drawstring and also longer leg length.

Great underwear!

These have got to be the most comfortable underwear and the company has such great ethics too! The customer service is amazing, above and beyond what most companies would do, so lovely and helpful!

Thank you so much for your amazing review Amy - they were such kind words and I really appreciate you taking the time to leave this feedback. I'm so pleased you like our undies and ethics - and our customer service - it really means a lot!
Please let me know if I can help with anything else and thanks again for your support. Best wishes, Sarah

Great quality and outstanding customer service

The boy shorts I ordered were a bit too small for me. I got in touch with Sarah who helped me with my return and sent me the right size without any extra charge even though I'm not living in the UK. I'm very happy with the quality and will definitely come back for another order in the future! Thank you Sarah, you've been fantastic!

Thank you so much for your lovely feedback Sophie, I really appreciate it. I'm glad you got the right boy shorts in the end and that you like them. Thank you for your kind words and do let me know if I can help with anything else. Sarah x

So soft

These knickers are lovely. I am a complete convert to organic cotton. Such a good cause too.

I hope they release new colours soon!
