Bought size 2T for my son's stuffed animal costume for Halloween. Knowing other reviewers may find them a bit small, they fit as expected. However, my son is very small (10th percentile) so it fits him perfectly, apart from having to roll his legs twice. For an average two-year-old, they can narrow a bit at the waist and chest. The quality is good, I was tempted to buy a second pair to keep for myself as I will be modifying them as part of his suit. As I mentioned above they fit well, the waist is in the right place but they are a bit long. Here are my son's typical measurements for comparison:
