There is a lovely young woman I work with who occasionally wears glasses around the office. Now, superficially she doesn't resemble Dorothy Malone, but for some reason, every time I see her in glasses I get a mental picture of this scene from The Big Sleep:
I tried to explain that to my beautiful co-worker, but it's hard to describe if you don't know the film. Update: After re-watching it, I'm amazed at how much they got past the censors. I'd forgotten how... charged it is.
(For the record, she is actually very ladylike and completely unlikely to lure a shamus into a bookstore with whiskey for some stockroom boom-boom.)
