Ordered it for my daughter who will be 3 in 2 months, is size 4-6T, don't think she will wear it at 5, my baby is a little taller than most kids her age but they run small out of. These tights are a bit bigger now, but I doubt they even fit 4 1/2 in. But I really like that they are thick, comfy, stretchy and warm, good for fall and cold winter when layered.
