I ordered size 5-6 for a child of 5 1/2 years. It was definitely too small for her, I was going to return it but decided to try it on my 3 year old and it fits her! Ha ha. so we're keeping it. Whatever there is to say, order if you can. Pictured is my 3 year old who normally wears a 2-3T in a size 5-6.
