1) Strapless bra
To wear some dresses or shirts that leave your shoulders exposed, you should wear a strapless bra. Leaving the straps visible, even if they are made of transparent material, is unsightly and would spoil the effect of your outfit. Indeed, the final effect would not be stylish at all. However, if you fear that your bra might shift or slide down, you can put this advice into practice. Without tightening it too much, you can try tying one of the two straps around the chest.
