Grab a measuring tape!

Let's measure your band and cup size together

Underbust Wrap the measuring tape around your body—over your rib cage and just below your bust.
LightBulb icon Shapertip: Was your measurement an odd number or at a half-inch mark? Round down to the nearest even number
Full bust Wrap the measuring tape around your body and over the fullest part of your bust. And be sure you’re not pulling the tape away from the front of your bust for the most accurate measurement.
LightBulb icon Shapertip: Did your measurement fall on a half-inch mark? Round up

How to measure

Step 1

Firstly, you'll need to gather your measurements. If you don't have a measuring tape handy, you can use a piece of string, a scarf, or even a long article of clothing to wrap around your chest.

Step 2

You'll be taking two measurements: the circumference around your rib cage determines your band size (underband), while the measurement around your bust will help us determine your cup size (overbust).

Step 3

Your cup size is calculated by the difference between your band and bust measurements. After obtaining these measurements, please refer to the bra calculator or bra size charts provided with each product to determine your cup size.
