My daughter is a slightly taller than average but petite size. She is about 42 inches tall and she is 30lbs. Her waist is pretty small and she normally wears 3T or 4T leggings and jeans for reference. These tights fit her well. They go pretty high up and aren't super tight fitting, so she might be able to wear them next winter too. They aren't super see through, but I still like to put little biker shorts over them for an added layer. The feet part isn't too thick and is comfortable inside a boot or shoe. The colors are true to the pictures, and I like how they look under her dresses.
