My 4 year old daughter went to dance class and she needed pink ballet flats. You were perfect. They're a bit long, but since they're hip, that's not a problem, and now she can wear them longer.
Pros
Excellent quality tights, fits well. My 5 year old daughter wears them to dance class every week and they are holding up well.
Cons
Tights can generate static electricity, which can cause clothing to stick.
