I worked in high tech most of my career. The only fashion statement was getting the tee shirt from the latest software release. At Apple, if you worked there a long time you had a closet full of tee shirts from all the projects you participated in. The female engineers didn't care how they looked and neither did the men.

I worked at an Apple marketing division for a while. There was a contingent of female Ukrainians. These woman spent serious time and money to look good. These woman just had high standards and weren't ashamed to look their best. And the women got along. And they were very approachable.
