This is the second tights my little daughter needs to buy for ballet. (The instructor requires the girls to wear footless tights). The first tights were made by Capezio but I found them too tight and difficult to put on my daughter. My daughter will be 5 soon, she is about 17" tall and weighs 41 pounds. I bought the pink ones in size 4-6 and they fit perfectly with little room to grow. I like them so much that I buy them in other colors for normal everyday use, I also like that they don't slip too much and are therefore a bit warmer for the winter, the price is also reasonable.
