My bra is giving me strap marks.
If the straps are adjusted too tightly they may cause the band to rise, creating awkward lines and discomfort. Try loosening the bra's straps. If that doesn't work, you need a bra that doesn't require the shoulder straps to do all the heavy lifting. A good bra has cups supportive enough to lift you without much help from the straps. If yours doesn't, you could be wearing the wrong size bra. Check your size and choose a bra with added lift or underwire for more support. A full cup works best. Fix it now and you'll avoid having permanent indentations on the top of your shoulders.
