How to measure at home

Measure your underbust. Wearing an unpadded bra or none at all, run the tape snugly around your ribcage, directly under your bust. Keep it level and breathe out normally.
Measure your bust. Run the tape around the fullest part of your bust. Keep it level and don't pull it tight — the tape should sit flat without compressing.
Find your size. Your underbust gives your band size. The difference between bust and underbust gives your cup. Enter both above and we'll do the maths.
