I would say they fit as expected but are also a bit large My daughter is 3 years old and I bought a size 4-6 because she is very tall and has very long legs. Most of their pants are a size 4 or 5. These tights fit perfectly in width but have a lot of extra length. I just put them together but I'm glad to know that the extra length means we can get more than a year out of them. They are very warm and therefore ideal for winter.
