Step 2 - Determine your cup size
Take a loose measurement around the fullest part of your bust, making sure the tape measure does
not indent the breast tissue.
Subtract the band size deteremined in step one from the bust measurement. The difference between
the bust measurement and the determined band size indicates your cup size:
- 1" = A cup
- 2" = B cup
- 3" = C cup
- 4" = D cup
- 5" = DD cup
- 6" = DDD cup
- 7" = G cup
- 8" = H cup
- 9" = I cup
