Ideas for fancy dress costumes?

It's for my partners with the best 21 and I HAVE to get dressed, but I'm serious about a block from what I can bring suit. There is no issue, can be anything. A friend suggested going to my boyfriend and I go as Borat Pamela Anderson, but I think it might be a bit crude for a 21. Also I would like matching a suit that Fred and Wilma, which my b / f, and I can go so close together. Any ideas? Please be creative, because I'm not lol.

One of you dressed in black, and one of the dress all in blue. You might even consider spraying your hair or face paint in whatever color they are. Walking with arms linked – you're a hit! Most creative costumes I've seen together.
