Half the fun of a nerd party convention is seeing how said nerds gussy up in nerdy ways for nerdy fun. What was once the province of portly sweaty white guys is now… well, it's still that, but there are a lot of women and a great deal of diversity these days, and it was certainly on display at the 2011 New York Comic-Con.
Check out this cosplay footage from the event. It was big on Homestuck, Poison Ivy and Ms. Marvel this year.
And if that's not enough for you, check out the NYCC hub for much more cosplay photography!
