This site has photos of more Slave Leias than you ever thought you’d see, plus instructions for making your OWN Slave Princess costume.
I liked this one in particular. The Star Wars Chick not only makes the costume, she models it and even though I worry about her inter-galactic obsession a tiny bit, I totally got past it since she is smoking hot. I kinda spent an hour or so there.
Man, I couldn’t even get my kid’s “Hobo” costume right…but if you’re handy with a sewing machine and soldering iron, give it a shot. Lemme know how it goes.
