On TV and in the movies, Sin City is hot, hot, hot -- so this costume is expected to be a top pick this October 31st. Purchasing this getup online or at a local costume shop is a sure bet, but why not roll the dice and give making your own version a try? With a little artistic effort, you can transform a plain cardboard box into your own customized slot machine. Cut out arm and leg holes and wear your creation over all-black clothing. Pass out silver toy coins to everyone you see. Jackpot!
