DIPUGBallet Tights for Girls - Thick Soft Footed Dance Tights for Toddlers and Kids

Does this still have the seams around the toes? My daughter has a sensory issue with her ballet tights and regular socks.

Do these tights have a cotton crotch?

Are these loose around the ankles? I have a very teeny little lady and other brands I've bought are so baggy around the ankle.

does it come as pair or single piece?
