I think most people in most modern societies would agree a line should be drawn somewhere.
If she wore a bikini to work, is it really fair to expect every guy to not say something? Now, that "something" should be closer to "you should change your outfit" than "I'd hit that", but still, the responsibility for the dress and generally accepted code of conduct falls on the woman in that case.
I don't see this stance as sexist because, as others have noted, we expect similar conduct from men.
But isn't saying "You're not dressed in line with our code for dress and appearance" the complaint here? I thought that with respect to low-cut/suggestive tops, the problem was never that they weren't professional clothing (with respect to the workplace in question) - which of course is an entirely independent and asexual issue - but that some people made inappropriate comments and thought it acceptable.
I think that a dress low-cut enough to be considered unprofessional is a sexual issue by default. Professional standards and decorum exist, in part, to prevent a sexualized environment.
How is it judged that a man's pants are too tight to be professional, or a woman's dress is too short, and what are the reasons? The reasons are sexual, and I might be wrong in this, but I would guess the line exists where people of either gender would begin commenting.
