If you're between sizes, we recommend sizing up for comfort.
Don't worry — it's quick and painless.
STEP 01
Measure Your Underbust
Wrap the measuring tape snugly under your breasts (where your bra band sits).
This number = your band size guide.
STEP 02
Measure Your Overbust
Now measure around the fullest part of your bust.
This number helps us determine your cup fit.
Some measuring tips.
● Measure while wearing a thin, non-padded bra.
● Keep the tape firm, but comfortable.
● If you're between sizes, choose the size that feels most comfortable.
