That's me, on the left. This is actually a picture from an afterparty from New York Comic Con, but I'm wearing the same thing tomorrow for Halloween. I'm Ramona Flowers, from this week's review book, Scott Pilgrim! (There's a jacket that goes with it... it was just really warm there.)
If you don't get the reference in the title, watch this scene where Scott is looking for information on this girl (Ramona) and asks his socially connected friend Comeau. I think it's hilarious.
And our friend Beth is in the middle, she's Roxie Richter (one of Ramona's evil exes). The girl on the right is Beth's sister... she is not in costume, but she is adorable.
