"My son is about a size 9, so I thought ordering the 10-12 would be perfect as I read reviews that said, "runs 1 size smaller." Well, the 10-12 was too small. I called, they were great and got the next size ordered for me and sent me a shipping label to send the small one back.
My son got TONS of compliments and was told it was the best costume they had seen all night!"
