My mom was Frankenstein last year for Halloween. We bought a very large man's suit at the thrift store & put my brother's old football pads under it. I did all the makeup & the hair is that fun fur stuff. The bolts I swiped from my sons kiddie construction set. (don't worry he's 12 now & he won't miss them!)
This was my husbands costume that we put together -- he cut up an old suit, put hockey pads on under his shirt, some green makeup, bolts, a head piece and.....the most important element - the 6 inch plateform boots. Caution they are a little tough to walk in so you'll need to practice.
