How do breast cup sizes work?
Bra sizes are based on your band size (the number) and your cup size (the letter). These measurements are usually determined by using a tape measure around your rib cage and bust. The number/letter is your bra size. Finding the right bra size is crucial for the right support and for a smooth comfortable fit.

Measure loosely around the fullest part of your bust. Subtract the band size from this measurement. Use this number to determine your cup size according to the table below. Example: if your ribcage measurement is 31, and your bust measurement is 37, your bra size is a 34C: 31+3=34, so 34 is your band size.
