I hadn't been planning on going anywhere, then got invited somewhere on very short notice, so I threw together this Christine Daae costume out of a blue cloak, red scarf, and blue dress I already had. And I have the exact same hair as Christine in real life, so that worked out too. :) I'd say it turned out pretty good for getting it together in five minutes.
Sorry about the laughable seriousness of the photo, none of my smiling pics turned out as nice, LOL.
