I bought size 4-7 for my ultra thin and tall 4 year old. It fit like it was made for her. Tights will never fit a 6 or 7 year old. Processed. 6 months after purchase. My nearly (56 month old) 5 year old is only 36 pounds but she has already outgrown them as they tie her waist when she sits down. I always wash on delicates and lay flat to dry so it doesn't get damaged. Still I recommend, but the size runs larger. I will buy the next size up because it is the best quality I have ever seen.
