I just enrolled my daughter who is 4 into dance and the shoe thing was hard for me too, they needed white buckled tap shoes and thank goodness the studio can order them. I only paid $19 for them. But my daughter wears a 9 and i got her a 10.5 and they are still a little tight I would go for the 6 she can grow into them. I am gonna have to order another pair i think. Also check thrift stores they might have some...most young girls shoes are in great condition. But good luck
