This was a fun variant of my "A New Hope" Princess Leia. I punched the lenses out of a pair of 3D movie glasses and made two large signs that read:
"I WAS A PRINCESS BEFORE DISNEY BOUGHT STAR WARS."
"THE EMPIRE? TOO MAINSTREAM."
I taped these signs together and attached them to a lightsaber to carry around. Everyone got a kick out of it, especially the Disney princesses. It was a lot of fun, and I hope to do it again sometime.
