We purchased for our granddaughter and she wants to wear it all of the time! I bought this costume with the pink LAGHCAT mermaid tail blanket and she wears them together! I purchased 5T because although she just turned 3 she is the height and weight of an average 5 year old. It fits but couldn't be any tighter to be comfortable. So I would say it fits about as expected or maybe just slightly smaller than expected.
