Memoi Flocked Heart Tights, Model MKF-4029 are great for dressy occasions. These run small like most microfiber kids tights so the average 7 year old girl will need a size 8-10. The Memoi Flocked Heart Tights have small hearts spread out all over the tights. In the photo the hearts appear white but they are actually the same color ivory as the tights. These are about 40 denier microfiber. 88% Nylon, 12% Spandex.
