- Do your straps constantly slip off your shoulders?
Your bra might not be the right style for your body type -- the straps might be too wide-set.
Women who are petite or have narrow shoulders often have this issue, and sometimes can't wear bras with wide-set straps.
- Do your straps feel too tight?
The straps should fit securely, but not tight -- check for red marks or indentations on your skin.
Your bra's straps are not solely responsible for providing lift and support -- that's a job for the back band and cups. They shouldn't feel uncomfortable, even if you wear a large cup size.
