a man costume is easy if you've got a few men around who are willing to lend you their duds. The best man costumes take the classy route, using a suit and a cigar. think Groucho Marx. The best part about a man costume is that you can play the part all night.

The Outfit
Get your hands on a suit. You can borrow one from a buddy or find one for cheap at the thrift store. The thrift store option is nice because then you're not obligated to return a suit that is in need of dry cleaning after a party. Don't forget the neck tie.
