My Halloween costume this year, Friend from 20th CENTURY BOYS. I'm hoping I can convince Peter that it'd totally be cool for me to sell anime to nerds at AN2010 wearing this. I'll need to get a grey (or black, according to the movie) suit to be completely on model though... I didn't have time to search for one this year, and, frankly, didn't really want to spend the money at the moment.
Also, I like how the Disco ball and various light flares and neon make me look like I have psychic powers.
