I bought 2 pairs of these for my daughters. They aged 6 and 7 but I bought the size up for each of them. They are slender but have long legs. The leggings fit perfectly, which is a rare find. Normally with leggings I have to go within their age group so that they fit them on the waist but then they end up too short in the leg. These leggings are made the same as the infant ones so cling to the legs like footless tights. My daughters are very pleased with them. They've worn them on their own and paired them with shorts and dresses. Very happy with them, I wish their were more designs.
