Yeah, what Chris said. A pencil skirt is meant to highlight curves, and it has been an office staple since the early part of last century, so I can't see why that would cause any offense. Assuming it's just a matter of fitting properly and not being too tight (tight enough to show that you're a woman, but loose enough to show that you're a lady), I can' t see any problems with this.
I think we have to be reasonable here. Women look like women. They have curves. One can't expect women to hide all the time, and pretend that they are just one of the guys. That is utterly degrading and sad. If that's the case, then let's all show up to work in burqas. Cleavage is one thing--I mean, it's basically showing bits of your bare breasts. I'll stick up for busty girls since we can't really help it, but otherwise I just don't think you're doing yourself any favors.
I think this is a very American thing, and a very unhealthy thing. We're so disturbed by a bit of nudity that ANY hints of a human body result in undue excitement. It's like how, during Victorian times, the sight of a woman's ankle was considered arousing.
Wasn't the whole point of the original "power suit" that it gave women more masculine proportions? Sorry, but I think I will pass. I can't be bothered worrying about what men are going to find alluring and making my wardrobe revolve around it. I am a modest person by nature, but I'm not prudish.
