MEASURING YOURSELF
Underbust
Measure firmly around your ribcage directly beneath your bust.
Bust
Measure around the fullest part of your bust while wearing a non-padded bra.
Cup Fit
Your cups should completely contain your bust without overflow, gaps or wrinkling.
Fit Check
YOUR BBM SPORTS BRA SHOULD
- Feel snug but comfortable
- Sit flat against your ribcage
- Keep straps secure without digging in
- Minimise bounce during movement
- Allow full freedom of movement
- Stay in place throughout your workout
If your band rides up, straps fall down or there is excessive movement, you may need a different size or a higher support level.
