I bought mine used from warehouse deals.  That was a mistake.  Is there no product quality checker at either the factory or amazon warehouse?  The center crotch seam was attached at the sides of the underarm seams.  Was this the rare collectible battle-damaged edition?  After some villain twisted Tony Stark's suit in half?  Since my child has two legs side-by-side and has not yet been twisted into an ungodly shape by constant super-villain battles, I undid the seam at the waist and resewed the whole thing.  It seemed easier than returning it and took approximately 30 minutes. If your child is in a normal child shape, I recommend purchasing it new, not from warehouse deals.  Or just be prepared to sew.  I gave it four stars for educational value because my son learned a fair bit about sewing that day.  :)
