I bought this to cover the sides of my bra because all the tank tops seem to be too big in the armholes and I do not want any part of my bra showing, ever. This does exactly what I wanted it to do. It's much lighter and cooler in the summer than a full cami. I am 36DD and the large fits me just right. I have a narrow back and shoulders but the straps did not slip at all and the cami did not ride up. I got the black and white and I love them. They work really well under anything sheer too, although of course it will be a cropped look underneath.
