Due to the nature of Bralettes, you may fit a few different sizes. If you’re unsure of your size, we suggest going with your underbust size (your underbust measurement correlates to your traditional bra number size ie. 34B). Support and coverage can vary from person to person, contact us for assistance if you’re unsure!
Please note sizes L-XXL provide more cup coverage. Model wears M/L on left, L on right:
Sizes 3XL-4XL have a higher cut cups and front for support:
