The under band is riding up
Lift up your arms to see whether the bra is tight enough. The under band should always fit firmly against the body.
The shoulder straps are digging in
If the bra straps are digging in, it could be because the under band is too loose and you are over-adjusting the straps to feel supported.
The centre fold is lifting away from the body
If it doesn't, the cups could be too small.
The back band is overstretched
The straps at the back should be parallel, if they aren’t it may be that your bra band is too small.
