These tights are very cute! I bought size 6-8 for my 6 year old daughter and was surprised that they fit perfectly. It's a bit big for it's age but I don't think they would fit a 7 or 8 year old unless they are small for their age. They stretch well but I noticed that when worn they sag in the crotch area so even stretching can be an issue for anyone over the average 6 year old. For reference, my daughter is 46 tall and 49 pounds.
