Correct me if I'm wrong... strippers/"exotic dancers" usually wear clothing more similar to the movie's costume than the stage costume.
I will give a bit of credence to your stripper bar argument. It seemed a bit more of a show than a stripper dive for the rich guys to go slumming in. But that's from a girl who's never been to a strip club, so that take for what it's worth.
"`I grow old... I grow old... I shall wear the bottoms of my trousers rolled.` What does that mean, Mr. Marlowe?"
"Not a bloody thing. It just sounds good."
He smiled. "That is from the `Love Song of J. Alfred Prufrock.` Here's another one. `In the room women come and go/Talking of Michael Angelo.' Does that suggest anything to you, sir?"
"Yeah -- it suggests to me that the guy didn't know very much about women."
"My sentiments exactly, sir. Nonetheless I admire T. S. Eliot very much."
"Did you say, 'nonetheless'?"
