I think a large part of women feeling 'empowered' by the 'power' they can have over men with the way they look/dress/act etc is that it makes men look stupid.
A man fawning over a pair of breasts or long legs is IMO pathetic, you wouldn't see half as many women going ga ga over a guy with his top off, we might say 'ooh, nice chest' but we'd get over it pretty bloody quickly!
Though it doesn't mean that we should have to choose to go down that route to make them listen to us, it is understandable why a woman in a good position will dress well, in a sharp suit, but with a skirt and heels, to use both her brain and her womanly figure to her advantage. IMO, that is just making the most of it.
We, as women, know that if we are dressed well and make an effort to look the part a man is more likely to give us the time of day, hopefully many of us then have the brains to back up the point that we deserve to be listened to.
The sending of pictures into tacky mags like nuts, is not in the same category though.
