Great for girls!
Size: 7-8 Years, Color: Black
My daughter LOVES wearing this. The shorts are detached so when using the restroom she doesn’t have to pull the entire outfit down. Plus the shorts have pockets and is great quality.

Poor Quality and Late Delivery
Size: 5-6 Years, Color: White
Besides arriving well after the promised delivery window and ruining my daughter's Halloween expectations, the costume is poorly made and ill-conceived. Attaching the shoulder pads with sharp safety pins is a terrible idea for young children, and besides, the pins broke off the first time I tried to use them. Snaps would have made far more sense! Several disappointed for the quality and shipping given the price of the item. Shame on this seller.
