How to tell if bra is too tight?

The straps of a bra are a useful indicator of how well the band is supporting your bust. If the straps of a bra slip down over your shoulders or dent your skin, that means that the band of the bra is either too loose or too tight and is forcing the straps to pick up its slack in terms of support. Also, a bra’s band riding up or digging into your skin are also signs that it is too large or too small for you. Your band should stay securely in place and its center—the part in between the cups—should lay flat against your chest at all times. Test the fit of a bra’s band by lifting your arms up over your head when you try it on. If the band rides up at all, it doesn’t fit you correctly.

What does it mean when your bra band is too loose?
