Helm: Foam board + cardboard at the back. Bits and bobs are water bottles and other things.
Apron/Shirt: Shirt is repurposed tee shirt with tea stains and acyrlic paint as the bloodstains. (Large red handprint on the back of the shirt.) Apron is broadcloth distressed with dirt and tea. Same blood stains.
Gauze: medical gauze soaked with fake blood (corn syrup, chocolate syrup, food coloring) and dried again.
Pants: plain black pants.
This was fun to wear, plus I had a lot of fun making it! The helm took all summer to design (maybe about 1 month), and the apron and shirt took me about 1 day to repurpose. The next challenge is making the great knife (oversized meat cleaver) that the character carries.
Too bad a lot of college kids didn't play the game...
