I’d be dressed like a writing desk, and let people figure out why.
I’d be wearing a toga and carrying a silver wine goblet.
Can I hazard a guess, or do you want others to figure it out on their own?
The penis costume is already taken. 
I suppose I would wear a green dress.
(No, not a real green dress… that would be cruel!)
And a red, round hat, like a pimento.
And I would strap on one of those military sashes and go marching about everywhere.
We like olives, yes we do
We like olives, how 'bout you?
Sound off! March forth!
…
um. yeah.
The answer would, of course, only be made up in an effort to appease the teeming masses. Flat notes, and all that…
If this thread were to come to the Dopefest dressed up I think it would look like this.
Long straight dark hair, hippie dress, acoustic guitar.
Leather armor, with a wolf skull (no jaw) upon each shoulder, and a crown of steel. A raven skull on a thin iron chain hung from my neck. I have a large beard, long hair, and many scars on my face and body. I’ll be carrying a large battle axe with hagalaz and tiewaz engraved upon it. I will come from that point upon the horizon where smoke billows up and I shall be riding a black war horse (with bright red eyes). In my saddle bag will be the skulls of all the kings who have fallen to me.
And maybe I’ll have two or three more axes for good measure.
White jeans, white shirt, red (well, more like “formerly red”) cotton sash tied correctly, red silk bandanna embroidered with the Chains. Red beret optional.
I guess I’d just come in the clothes that I slept in last night.
I would come like this and I would be right on top of the bar counter and you could scratch my tummy if you got me a beer 
And I would come like this.
Having taken time out to buy Kotick a beer and scratch his tummy, of course.
Hmmm interesting Zombie thread. The Mods will probably leave it open.
I would wear a pair of Garden State Parkway Exit signs. Something Like this.
Jim
I’d just come as myself and carry a photo of Deb. (That was how I got the down payment to our house.)
If I came dressed as the original meaning of my user name, I’d look something like this. But based on what people seem to think of when they read my name, I guess I’d dress as Chewbacca. With a pint of beer, or course.
I would dress as an Amazon and ride around bare-breasted, dazzling the dopers.
