Which Costume Should We Choose?

We are looking for Halloween costume ideas, but the catch is it has to be a famous trio. I've been pushing Star Wars characters for years. Rik as Han Solo, myself as Luke Skywalker and Michele as Chewbacca JK LOL I mean princess Leia.

Last year we went as The Band Perry and it was a hit. So tell us your suggestion and we will decide next week on the show.

Famous Trios with two guys and a girl:

Mario, Luigi, and Princess Peach

Lady Antebellum

Batman, Robin, and Cat-woman

We want all of your suggestions!
