The 3-5T fits my 38" 2 year old girl, she is 98th percentile and will be 3 years old in 3 months. There is a bit of excess on the ankles so I know she's in it can grow but not so much that it looks bad I'm not sure if they will fit a 4 or 5 year old unless they are small The color is not what I expected I got ordered pink, when i received the package i thought they sent me pink ballet flats instead, but overall when i put them on a child they seem like good tights for the price.
