Wrap a soft measuring tape snugly around your ribcage, directly under your bust. Keep the tape parallel to the floor and breathe naturally. This measurement gives you your band size.
Measure around the fullest part of your bust, keeping the tape parallel to the floor. Do not pull too tight — the tape should sit comfortably against your skin. This gives you your bust measurement.
Subtract your underbust measurement from your bust measurement. The difference determines your cup size. For example: Bust 90cm − Underbust 75cm = 15cm difference = C Cup.

Fitting Tips
For the most accurate result
A flexible fabric or plastic tape measure gives the most accurate results. Avoid using a rigid ruler.
Check that the tape is parallel to the floor on all sides, especially at the back.
Having someone else measure your back ensures a more precise and even measurement.
If you fall between sizes, we recommend sizing up for comfort, especially for G and H cup styles.
