Guía de tallas - Atom 2.0
What size do I choose?
Bum bikinis are designed to cover the essentials. We strive to make all our clothes adjustable so that they can adapt to different body types.
⚠️ However, please note that we do not follow a standard sizing system as our bikinis are small and low-rise. Therefore, when in doubt, we recommend sizing up.
ATOM 2.0 TOP
Your size will depend on how you like your bikinis to fit. If you prefer a top with minimal coverage, we recommend size S. If you want a bit more coverage, go for size M. Size L is best suited for larger busts.

These are the top's measurements:

ATOM 2.0 THONG
If you prefer a low-rise thong, go for size S. The back coverage is the same for both S and M, so if you’d like a bit more height in the front, choose size M.

If you need our recommendation to choose your size, contact us at hola@bumswim.com or via WhatsApp.
