The Racerback tank top is incredibly comfortable, made from ultra soft cotton (92%) spandex (8%) and designed with a built in shelf bra. The perfect tank shirt for all occasions and black goes with just about anything! Wear it with a pair of jeans or sleep in comfort with the support from the built in bra. Detailed with a small bow on the front left and the racer style back is great for tying a ribbon around and adding a little more color. Our tank tops look great with all of our lace and cotton boxers or thongs!
