I think this is something where people see someone walking/talking/otherwise being out and about that is obviously a woman, no way they could be a man, but they act a bit less feminine than a lot of other women but they aren't called anything but a female. Perhaps a couple great examples of someone who acts very natural, if not a bit awkward, could be Jennifer Lawrence and Kristen Stewart. I don't see anyone saying "Oh they aren't a woman cause they don't act super feminine."
This applies the other way as well. It's just a matter of having and owning a presentation. You don't have to be like a model or even like a lot of the actresses to be seen as female. If you didn't see any of the upper body, and only saw some legs in coveralls underneath a car you might think "man" but if you saw a pair of bare shaved legs wearing a pair of short shorts leaned over the fender of a car with only a little glimpse of the upper body, you'd probably think "woman," why? Cause we are taught that short shorts and shaved legs are a feminine trait that women display, despite the fact that working on cars is still (at least in a fair amount of areas) seen as mostly as masculine trait.
