Villains of Gotham Costume

I am the joker, my girlfriend is harley quinn, her best friends are poison ivy and cat woman, and our other friend is the riddler. We chose this theme because it fit us so well. Each of us already looked like our character and we're all huge fans of the villains of DC comics! All were homemade except for the harley costume. Joker cost about $35, poison ivy $40, riddler $25, and cat woman $15. The joker costume was all found at goodwill and so was the riddlers costume. Cat woman was made from things we already had and from walmart and halloween stores. And for poison ivy we found a single piece bathing suit at target and ivy leaves at old time pottery and hot glues them on. We used a piece of fabric from walmart for the sash and dyed some tights with koolaid. Harley's costume was $45 and the mallet was $20 made out of a dowel from Home Depot and cake boxes from Hobby Lobby.
