im not going to read that article, but Id just tell you make sure you don't dress provacatively. There is nothing more distracting than a girl who wears something too tight, short, or revealing. Its just torturous.
P.S. Girls always seem to think something isn't provacative when it really is very sexy. That's not appropriate for an office so you should probably dress more conservative than you think you should.
I think business casual is pretty appropriate. In my office girls can wear skirts above the knee as long as they're within fingertip length, open toed shoes are OK as long as they're not flip-flops, and tops can bare shoulders but not be spaghetti strap thin. Jeans are permitted on Fridays, t-shirts and sneakers are never allowed. Guys in my office generally wear casual slacks and button downs with loafers.
But I used to work in a construction firm where jeans, t-shirts, and sneakers were the norm. Though there was no sense in dressing up there because everyone was often covered in paint, sawdust, etc.
depends on what type of office you work at. for most places I say no jeans or denim, your shoulders should be covered, shouldn't be obvious cleavage showing, skirts should be longer than mid thigh, not much shorter than a few inches above the knee, heels shouldn't be outrageously tall (maybe 3-4 inches), nothing skin tight or overly bright and no slits up to your ass. fitted is fine though. and I don't think you need to wear pantyhose every day.
