Costume Swap

If you still don't know what to be for Halloween, before you take scissors to a perfectly good white sheet or hastily fork over $50 at a store, see if you can trade or borrow a costume from one of your friends. Although you've been saving your Harry Potter costume in case J.K. Rowling writes more books, maybe it's time you let someone borrow it so you can go to your parties dressed as Batman (he'll never go out of style). Sharing costumes saves you money and lessens your consumption habits - two good things that are never scary.
