By "classic," I mean a character that's been done to death, but is a fan favorite anyway.
Bonus points if you do the character with a twist!
For instance, I just did Duo Maxwell at Youmacon in Troy, MI this weekend. My twist? Check it out!
(I'm the second picture down on this page.)
It's not the greatest costume ever (I had to throw it together in a day and a half), and my braid wasn't nearly long enough, but I got a lot of people who liked the "oh-so-pitiable-prisoner" idea. I think I'm going to try to put together a better Duo for Ohayocon--and then bloody up again.
So, who else out there is cosplaying a "classic?"
