Many people thought the Marvel themed party was too much for a boy to throw for my daughter's 3rd birthday. But with this costume it all made sense. She ended up looking so cute looking like her favorite Spider-man but still looking like the girl she is too. I loved it. This was a size 3T-4T but my daughter is so petite that I actually had to alter the closure for it to not be so loose. When she first tried it on her whole chest showed. It wasn't a biggy to sew it up a little for me since I have a sewing a machine and more hook and loop closures lying around but this might need to be considered for those who do not sew. The length was fine.
