Of course the question was for the ladies, but here is my two centavos.
I think many times, a lady overlooks the fact that a clean and pressed mans dress shirt, a pair of sexy panties, some heels and light make up can be the sexiest outfit ever. Add a pair of "bookworm" eyeglasses, and whoa nelly!
And, just a touch of the right color lipstick can transform an average look into smokin' hot.
