How to fit your bra

Underband

The band should sit horizontal across your back and feel snug but comfortable. You should be able to fit two fingers easily under the band.

CUP FIT

Ensure the centre front of the bra sits flat against your chest. The wire should not sit on the soft part of the breast. The cups should be completely filled with no excess fabric. There should not be any over spilling or bulging at neckline or at the underarm.

STRAP FIT

Adjust the straps so you can comfortably fit two fingers between the strap and your shoulder. They should not slide off your shoulders or dig into your shoulders.

Bra size guide: helpful hacks for finding your fit

Choosing the right hook.

Choosing the right hook

We recommend trying your bra on using the hook closest to the outside as the material stretches over time.

Apply the finger test to the band.

Apply the finger test to the band

Trying the '2 finger test' to the band ensures that you can comfortably insert 2 fingers between the band and your back, indicating that the bra isn't too tight.

Check the cup fit.

Check the cup fit

Bend over when trying your bra on, and secure the hooks before you stand up straight - this way, you settle into the cups properly.

Check the centre laying flat.

Check the centre laying flat

The centre of your bra should always lay flat against your chest. If it doesn't, you are likely wearing the wrong band size.
