Red Alert! Great game, but not what I'm talking about.

I will be attending the Midwest Media Expo in Detroit the 2nd week of April and I'm so unprepared!

I probably don't need to, but there's this overwhelming sensation of panic that I get for trying to attend a convention in street clothes.

So my question is.. Who's going to be there? Do you happen to be a cosplayer? Do you have any ideas as to where I should get my fabric?
