"I bought the large 8-10 size for my 6 year old (who is 49 inches, 50 pounds). The dress fits great - a taller child would find it pretty skimpy. Belt ties on, so is easy to adjust. The wristlets are fun and fit well, but the boot covers are too small to cover her size 1 shoes, and the elastic on the mask was too short to fit comfortably around her head. This was easy to fix - but a surprise. However, my little superhero loves this costume and it's holding up well through multiple events."
"This was a great pick for my 4 year old who usually wears a 5 or 5T. It is a little long on her 41" height - so moms with shorter kids may have to pin it up/hem it. This is not super-easy, as there are multiple layers of fabric and trim at the bottom. However, the fabric is thick, warm and pretty, with lots of sparkle. The hat stays on well in all but the windiest weather. My little witch loves it!"
