I used these when I was taking ballet, but I'm selling them now that I've quit. The one on the left has an open back design. (Size M) The one in the middle also has a ribbon on the back, making it very elegant, but the black color also gives it a cute look. (Size L) The one on the right is a light pink color and is a lovely color. (Size L) The items below are all free size. Only sold as a set.
