The picture in the entry seems to illustrate clothes that is just a slightly feminized version of a man's suit. Bleagh!
I am a man, and the offices I have worked in function best when women are not treated like the men folk, who, for the most part either don't care (and are somewhat relieved) if there is an easily followed unofficial dress code or will dress as slovenly as they can get away with.
Women want to wear clothes that flatter them, or at least don't emphasize problem areas, and colors that suit them. Not all of them want to rely on "accessories" to make their statement. I suppose some things might be over the top, and certainly revealing get-ups aren't suitable for the office, but if a woman wants to wear a floral print satin dress, it doesn't necessarily make her less productive. It might even make the office cheerier. Healthy men like to have women around who don't dress like Sigourney Weaver in Aliens, or a calcified school marm.
