To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have a rather petite JUST barely 3 year old and these fit her well - when she also is still wearing some size 18m pants, and some other 3T pants literally fall off of her. They are a thicker type of pant/legging, but not super thick just not the thin jersey type material some are made of - they are actual pants. The colors were as expected, we're pleased with them! :) But buy a bigger size than you think you might need!
