Why Fit Checks Matter
Studies and fitting-room surveys consistently find that most women wear a band that's too big and a cup that's too small because they were sized once, years ago, and never re-checked. A quick fit check like this one catches the two most common issues in seconds: a loose band doing none of the support work, and a cup that's too shallow for the volume it's holding.
Common Fit Problems, Explained
- ✓Band rides up: band is too big go down a band size, up a cup letter (sister size).
- ✓Straps dig in: band isn't carrying its share of support tighten the band, not the straps.
- ✓Spilling over the top: cup is too small try the next cup letter up.
- ✓Gapping or wrinkling: cup is too big try one letter down.
