My daughter wanted to be Jessie the cowgirl for halloween but it was not available in the stores.  So I turned to my ever dependable Amazon.  I was reluctant to order because my experience with the costumes-in-a-bag has not been all that great.  But I was pleasantly surprised with this purchase.  My daughter is very tall and thin and I feared that like most of her clothes this would require alterations on my part. But it did not! It is designed with an elastic insert at the waist in the back which made the costume fit nicely without looking baggy.  The hat came a little bent from the shipping I guess but still looked great.  It does NOT have an elastic band that goes under the child's chin.  I found this hat fell of constantly when she was trying it on so I simple modified it by poking small holes in the sides and adding an elastic strap. This made it work perfectly.  My daughter got a ton of compliments on her costume because it was rare (since it wasn't available in stores).  Overall I was very happy with this product.
