Find your fit
Your perfect fit starts here.
Because the right support starts with the right fit. Grab a soft measuring tape and wear a non-padded bra (or none).
01
Measure your band
Wrap the tape snugly around your ribcage, directly under your bust. Keep it level and breathe out. This is your underbust.
02
Measure your bust
Wrap the tape loosely around the fullest part of your bust, keeping it level across your back. Don't squash.
Size finder
We use the UK method: your band is your underbust rounded to the nearest even inch, and each inch of difference between bust and band is one cup.
Enter your measurements to see your estimate.
How cup sizing works
A cup letter only means something alongside its band. A 34F and a 38F hold different volumes. UK cup steps (inches of difference):
| D4" | DD5" | E6" | F7" | FF8" | G9" | GG10" | H11" | HH12" | J13" |

Does it fit?
- The band sits level and snug on the loosest hook
- The centre front lies flat against your chest
- No spilling over the top or sides of the cups
- No gaping or wrinkling in the cups
- Straps stay put without digging in — the band does most of the work
