I would think people would recognize Elizabeth Bennet. I love that book.
I'm guilty of Juliet Butler from the Artemis Fowl book series. I wore it for a premier of the latest book, but no one recognized it, even with the jade hair ring and glittery eye shadow. I really hope they get made into an awesome set of movies! If you don't know them, they are by Eoin Colfer, and they are a young people series like Harry Potter, but smarter. I've enjoyed them from teen-hood onwards.
Cosplay ALL of the ponies!!!
