"While the costume is very cute and well made, please be aware that this costume runs extremely small. (Thus the 3 star rating.) I purchased the size 4/6. My daughter is on the small side - just about wears a 4T and this costume is snug around the body area (from the waist up). It just about fits her. Not much room for a shirt to fit underneath. Never expected that to be the case. This would never fit a child who is larger than size 4."
