Query: Materials are too flimsey and the sizing range is too wide.

When a child is going to be playing with a product, it needsd to be constructed of more durable materials. This is not the case with this item. It is made of very flimsey material. Also, the size range is too big. Small, medium and large should be eliminated and costumes should be made according to size, i.e. 4, 6, 8, 10, 12, etc.
