Come...as you aren't?

Last night, I received an invitation for a party which has a theme of "Come As You Ain't". It's pretty self-explanatory: You basically come dressed completely the opposite of what your personality is. In other words, if you're a punk rocker, then you're supposed to wear really "preppy", conservative clothes...or if you're pro-Obama, you're supposed to wear a pro-McCain shirt or button, or whatever. In trying to come up with what I would wear and what opposite (doppelganger?) personality I would be trying to convey, it really got me to think about who I really am...because you have to really know who you are in order to figure out who you aren't...But in my case...well, I've often "decided" that I'm not "this" or "that"...but never spent as much time thinking about who I am...
Ironically enough, the two ideas I've come up with for how to dress for the party are total opposites. My first idea is to dress like a sorority girl (which I've always felt was "not me") and the other is to dress like a total hippie (which I'm also beginning to realize is not the kind of person I would want to be either). So what are the opposite of those two things? Does this make me, in reality, a middle-of-the-road stick in the mud?

So...I have two questions:
(If you know me well enough) What kind of person/personality do you see as being the complete opposite of mine? In other words: what would you see me wearing to this party?
And: If you were going to this party, how would you dress up?

Natto smile!

It was natto night tonight (try saying THAT three times fast ;-)) and without meaning to, I did this with the accompanying packet of mustard:

Sure you don't wanna try some? ;-)
