How to Measure
Measure your band size by wrapping a tape measure snugly around your ribcage directly under your bust, keeping it level (round to the nearest even number for US/UK band sizing). Measure your bust size around the fullest part of your chest. The difference between bust and band measurements (in inches) determines your cup size — each inch of difference corresponds to one cup size letter (A, B, C, D...).
Notes
US and UK band sizes use the same numbers, but cup letters can diverge at larger sizes (a UK 'DD' is often labeled 'E' or similar in European sizing) — there's substantial inconsistency between brands at larger cup sizes in particular. EU/France band sizes are calculated as US/UK band + about 15-16 (approximately converting inches to a centimeter-based band number).
