Not being a woman, I obviously can’t speak personally to the question. But I will observe that when I was growing up my sister and my friends and lots of other women were pushing back against the social obligation to wear dresses.
In the conservative, Evangelical Christian world we were part of and that was dominant where we lived, women wearing pants were considered scandalous and sinful. So women fought for the right to be able to wear pants, which they say are more practical and comfortable than dresses.
I mean, even as kids, girls in dresses were at a decided disadvantage when it came to playing equally. Dresses aren’t suited to the sort of rough and tumble play that misogynistic mores hold are "wrong" for girls.
That’s one take, anyway, for why many women don’t wear dresses.
