The 3-5T fits my 38" 2 year old girl, she is 98th percentile and will be 3 years in 3 months. Excess at the ankles so I know that she can grow in it 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 isn't what I like I expected pink, when I received the package I thought they send pink ballet slippers instead.But when I put it on a child they are white.Generally good tights for such a price.
