How US cups translate to UK cups
US and UK cup letters often match through D, then split. A US DDD/F commonly maps to a UK E, and higher cups shift into UK double-letter labels such as FF and GG.
Use conversion as a starting point
A converted bra size is the closest label match, not a guaranteed fit. Wire width, cup depth, stretch, and brand grading can all change what feels best.
Adjust with sister sizes
If the cup volume is close but the band is not right, sister sizing can help you keep similar volume while changing band comfort.
