A bra band that rides up means the band is too big. If your bra band isn’t parallel to the floor and riding up try a smaller band size.
The bra band provides up to 80% of the support for your breasts. If it’s not snug, then it’ll start riding up. A correctly sized bra band will fit tight at first, but not uncomfortable, on the loosest set of hooks.
Remember: if you size down in the band, go up a cup size. For example, from 32A to 30B. Check out our sister size guide.
