Lead the Rebel Alliance to victory in a Princess Leia costume!
Sexy to catch Han Solo's eyes, but strong to kick Jabba the Hutt's ass, this costume works for all the sides of Princess Leia. As one of the Star Wars' icons, it'd be a great pick for that party, be it in the Princess Leia slave costume or any other version.
Pull out a gun and get some action going. May the Force be with them!
