Let's put it this way, they definitely love a woman that looks good. More classy then slutty, form fitting clothes, not slutty tight. The times I have met them, I was usually wearing a pair of form fitting blue jeans and a tighter top, and yes, showing some cleavage. NOTE: some, not all! Like I said, classy. Whatever it is that looks good on you, whether its too much for someone else does not matter. Don't wear something that will make you feel uncomfortable, trust me it shows.
