Problem: This is a fabulous costume! My daughter loves it and has had it on every day since it arrived last week. She even slept in it a couple of nights. The other reviews are correct in saying that it needs some mending. We had to reinforce the velcro on the mask and the elastic on the bottom of the boots. After a little stitching it is fine. We also sewed on a small piece of material to the back of the face mask so that it wouldn't stretch any further and tear. This was a fabulous idea. Do it! I only deducted one star for this because the rest of it is great. The material is a durable shiny pink. My daughter is a size 4 and wears a size 9 shoe and the small fits perfectly. If she were a 5 or older I would get the medium. Totally worth the money.
Solution: Positive
