Cute costume and will serve its purpose for Halloween, but it has been way more trouble than it's worth. My daughter wears a size 3T, so I originally ordered the toddler size. It wouldn't even go over her torso. I ended up returning it and ordering the child's small which said it would fit size 6-8, and it fit great...except for the elastic in the sleeves which would even be too tight for my one-year-old's arm. My daughter is petite, so this is never an issue. I removed the elastic, turned up the sleeve, restitched, and put in an appropriate sized piece of elastic.
