I made this mock straightjacket for a Lovecraft-inspired LARP I ran called Gods of Forbidden Light. It is fully functional, but lacks the traditional crotch strap because I didn't want people getting too friendly with each other when attempting to put it on someone. It is made entirely out of white cotton duck and zips up the back with a silver jacket zipper. The straps are grommeted and buckle into silver buckles sewn into the side seams.
