Fix a slipping T-shirt
I have a front and back very low cut T-shirt (see photo), which slips again and again from the shoulder. To attach it, I sewed on both sides of the inside of the shoulder seam along a small loop of rubber cord, each with a snap fastened to it and attached along the warp seam to the neckline hem.
I put the loop around the straps of top, bustier or bra, as you like and close the push button. That keeps the whole day bombproof. And if I wear a sleeve T-shirt underneath, you will not see the closed loops.
