I think you can argue that about makeup for example, I think that's a really simplistic approach to the reasons women use makeup.
Put it a bit differently - make-up is gendered in our culture, wearing it at all, or wearing it in particular ways. As such, it's largely about emphasising one's femaleness as opposed to maleness.
Individuals might wear it for all kinds of individual reasons, but that's it's cultural role.
The reason humans overall are interested in social signals that emphasise their sexed differences is because we are really interested in sex. It's pretty deep-seated because it's so important to our survival as a species. It's very difficult to make people not notice sex, and even so many people, especially when younger, have a real interest in emphasising it.
But if we want a workplace that de-emphasises, as much as possible, sex differences, doesn't that suggest that we should avoid anything that draws attention to our sex?
My feeling is that would be a complicated proposition, but then we'd have to ask to what the implications of that are. Some cultures have thought that men and women - again, at the whole society level - essentially can't work together without sex getting in the way and so it should be avoided in various ways. Interestingly, when #MeToo was big, I saw some suggestions from some women that seemed to parallel that thinking.
