In fair condition, some wear to the knees and the back has hook and loop closure that has snagged the material a bit. Still lots of life left for another child. My kids liked this costume. I would say it fits true to size.
I washed it and is ready to use.

Forget grabbing candy by hand—use this awesome Spider-Man loot and scoop treat bag to do the work for you! This cool treat bag will perfectly complete any Spider-Man costume.
