Does the band ride up your back?
If yes, your bra is either too large or needs to be tightened. If it's still too loose after you've adjusted the band, it's time to go down a band size (and possibly up a cup).
Does your breast tissue spill over or bulge under the cup?
If yes, your cups are too small, and you need to go up a cup size.
Do the cups pucker or gap?
If your breasts don't fill out the cups, your bra is too large.
Do your straps slip and slide?
If you've adjusted your straps and they still fall off, either the band is too big or your bra has lost its elasticity. If you have sloped shoulders, opt for a racerback bra or a style with convertible straps.
Do your straps dig into your shoulders?
If so, try loosening the straps. If that doesn't solve the problem, it's likely the cups are too small, and you need to go up a cup size.
Does the wire poke and prod?
If so, you're wearing a cup size that's too small.
• Spillover on top or sides
• Center section doesn't lie flat
• Underwires poke or ride up
• Cups wrinkle or gap
• Adjusted straps still slide off

1. Put on your best-fitting non-padded bra.
2. Wrap a measuring tape snugly around your rib cage, just beneath your bustline.
3. Straighten the tape so that it's parallel to the floor.
4. Exhale deeply—you want the smallest measurement possible.
5. Round to the nearest whole number and refer to the size chart below.
Tip: Because bra bands tend to stretch over time, your bra should fit firmly on the last hook when new.
