This costume is super cute but is WAY LONGER than other costumes this size. My daughter wears a 3t but usually has no issue wearing 4-6x dress up clothes. I got this for her for Halloween and had to pin it up at least 6 inches. When we started trick or treating, it was still dragging and causing her to trip so I had to pin it up another six inches or so. At least she'll have plenty of growing room ;)
