Fit Guide

Find your size in 60 seconds

Our bras are engineered specifically for AA, A and B cups. That means the fit is different — and better — than a standard bra sized down. Here is how to find yours.

1. Measure your band

Wrap a tape measure snugly around your ribcage, directly under your bust. Keep it level and exhale. Round to the nearest even number — that is your band size.

2. Measure your bust

Measure around the fullest part of your bust, keeping the tape loose enough to slide two fingers underneath.

3. Find your cup

Subtract your band from your bust. The difference gives you the cup:

Difference	Cup
Less than 1 in / 2.5 cm	AA
About 1 in / 2.5 cm	A
About 2 in / 5 cm	B

Between two sizes?

Go for the smaller band and the larger cup. A band that feels slightly firm on the loosest hook is correct — it will relax with wear.

Still unsure?

Order two sizes. Returns are free for 30 days, so keep the one that fits and send the other back. No questions asked.

Replace these measurements with your own supplier's specifications before you go live.
