Some fun costume ideas for a group are to go as The Blue Man Group, a team of superheroes, or characters from the game "Clue." Another group costume idea is to dress up as the cast of a favorite movie or TV show.
To dress as The Blue Man Group, have each person in the group wear all-black clothing and paint their faces and hands blue. Alternatively, have everyone dress as a different superhero and go as an unstoppable crime-fighting team. Dressing like "Clue" characters can be a fun group costume. A trip to the thrift store is sure to yield enough finds to create a convincing Colonel Mustard, Professor Plum or Mrs. Peacock.
Dressing up as the cast of a TV show or movie is another fun way to don costumes as a group. Some popular movie-based group costumes are to dress as characters from "Star Wars," "Harry Potter," "Mean Girls," "The Addams Family" and "Napoleon Dynamite." Some fun TV-show-inspired group costumes are to dress as the "Seinfeld" cast, the "Big Bang Theory" cast or as cartoon characters from animated shows, such as "The Simpsons," "King of the Hill" and "Futurama." Dressing up as a rock band or other performing group is also a fun option.
