These traditional stretch, razor back tank tops have been a staple in Vitesse product line since the beginning. They are great to layer with or to wear during activities or even sleep in. They are soft, comfortable, and affordable. Lots of colors to choose from. I am a size 6 and have a 34DD chest. I can fit in all three sizes but prefer a medium or a large. I can't tell a ton of difference between the two but I do feel way to tight in the small.
