***Due to the higher-waisted style, these mid-rise bikinis are a more generous fit than the low-rise bikinis so you may find you can wear one size smaller. ***
Our women’s mid-rise bikini has been developed in response to customer feedback about having a bit more coverage, so hopefully these will become a firm favourite. This light grey is a flattering shade that complements any light wardrobe.
- A mid-rise style providing more coverage over the stomach and a higher leg
- Made with GOTS Certified Organic, Fairtrade and PETA-approved cotton
- Ethically produced in India
- No internal labels for a smooth fit and no VPL.
For every pair of underwear you buy, we donate TWO pairs to the charity Smalls for All.

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: |
