Black Widow and Tony Stark
Become Marvel characters for a night without the fuss of heavy, tight-fitting costumes.
What you need to do: The guys should wear a Red Hot Chili Peppers tee. To get the light beneath the clothes, cut out the shape of the Iron Man logo and stick some glow lights under the shirt. For the girls, find any black zip-up hoodie or shirt with a matching black belt and trousers. Stick the logo on your arm.
