How to Measure

Align a measuring tape directly under your bust, keeping it parallel to the floor. The tape should feel snug but not tight around your body.
Use the chart, find your band size.
Band Size / Measurement
1. Find your cup size
Wrap the measuring tape at the fullest part of your bust, keeping it parallel to the floor. The tape should fit comfortably around your body.
Subtract your band size from your bust measurement. This bust-band difference determines your cup size.
* If your bust measurement is 36” and your band size is 32, the bust-band difference is 4”, indicating a D cup.
