1. RIB CAGE MEASUREMENT

Measure around your rib cage (at the bottom edge of your bra) just under your breasts. The tape measure should be snug where you can just fit two fingers underneath. If you measure between inches, round down to the nearest full inch.

2. BAND SIZE

Using our measurement guidelines, find your corresponding band size based on your rib cage measurement.

3. BUST MEASUREMENT

Measure loosely around the fullest part of your breasts, usually through the high point.

4. CUP SIZE

Subtract your actual rib cage measurement (step 1) from your actual bust measurement (step 3). The difference in inches is your suggested cup size. If the difference is between sizes, round up.
