I am not sure on this one. I did have a lady friend from Chicago. A real débutante. She had some rather chic outfits (actually a storage locker filled with them), like Sacs 5th Avenue attire for cold climates (i.e. quality coats with fur color and fur inside).
I however am still not sure...
Chicago is urban, and considered "East coast" even though I guess it technically isn't.
The word "mid-western" generally implies small town people in America's heartland or some bullshit like that. Las Vegas is technically the mid-West, I think, and I certainly wouldn't go to that casting call dressed in next to nothing.
