I really don't think women who dress provocatively, or wear those word-on-the-butt pants have much of a leg to stand on if they complained that guys were staring. Although most ladies that dress in that manner don't really mind the attention and wouldn't complain. Those that do complain probably only want certain ATTRACTIVE men to stare, and will only complain about uglier guys. Because, you see, these chicks are shallow, conceited, and are taking the entirely WRONG approach to feeling/looking attractive.
And if you think about it, these girls that are complaining are probably just doing it for the extra attention. They may be saying, "Ew, can that guy PLEASE quit staring at my boobs?" but what they're really saying is, "I want everyone else to hear about how I'm getting stared at, because it gives me an even bigger head to tell people about it." They may act like they hate it, but they love to take the opportunity to shine the spotlight on themselves at those moments.
I, naturally, have very big "assets" on my otherwise thin frame and I get stared at enough without wearing low-cut or tight tops. I don't like the looks I get from men sometimes, but the only time I'd start complaining is if I actually felt unsafe. If you're attractive to a guy, you'll get stared at even if you're wearing a snow-suit. Or maybe that's just because snow-suits are ridiculous.
