Costume ideas for a "Master of Ceremonies" for next year

Hey all!

I am going to be the queue-line host for an area haunt next year... we are going to be completely interactive, with a lot of crowd participation.

I will be up-front calling contestants to play games, answer trivia questions, etc...

so... i need an appropriate costume!

I am having a hard time thinking of ideas... so, I wanted to throw it out here to see what you all could come up with!

Here's how I need to costume to function:

1. versatility for appropriate weather.
--- this is mostly an outdoor haunt, with the queue being outside... we experience VERY dramatic swings in temperatures ... 80 degrees one night, 35 degrees the next

2. comfortable
--- since I will be in this all night, being the face of the haunt... I will want to be fairly comfortable. I have worked in this haunt as an actor for the last few years, so I am accustomed to wearing costumes for several hours a night... but being an actor, I can get a brief break from time to time to adjust my costume. ... in this role, I will not be able to do that as easily.

3. wow-factor.
--- I will be the 'face' of the haunt... I want people to leave the haunt thinking that 'the MC looked pretty scary/cool' ... I have thought of being a 'carnival caller' type of character, but that just isn't very exciting. I LOVE doing makeup, so I wouldn't be opposed to doing that.

so... any thoughts, my friends?

I was thinking of doing a throw-back peirrot clown (only black and white makeup) or something similar... but clowns are kind of cliche (this coming from a guy who is going to be a clown for halloween this year).

Thanks in advance!!
