dress as a farmer with a plaid baseball cap. There's a photo of him with that hat. Under a jacket you can always be wearing his "skin vest" get a pair of those plastic breasts. He also made a nipple belt. Too bad he's less of a serial killer and more of a grave robber...

Ed Gein, looked fairly normal for his place in time. He dressed as most men of his day did: work pants and long sleeved shirt (sleeves rolled up to elbows) and a hat with a brim with good sturdy work shoes.

This site includes one of the most popular pictures of Gein: http://www.carpenoctem.tv/killers/gein.html

He dressed a bit like a murderer.
