For cosplay, you need to think of books or movies that you like. Think of something you've watched or read recently -- or something from long ago if you have a favorite from back then! Most people dress up as the most popular thing of the moment, but my favorite sorts of costumes are the ones where the people put a lot of work into them and obviously really liked the book or movie (or video game). You could also use Google to search for "cosplay ideas" or "most popular movies of 2012" or other ideas.
