I came across some interesting thoughts on unisex fashion in "Looking Good", published in 1976. The author, Clara Pierre, was writing from the perspective of an industry insider observing what she expected to be permanent changes in fashion. In chapter 10 "From bralessness to unisex", she explains the connection between sexual liberation and unisex clothing as a process of increasing comfort various aspects of sexual identity and expression:
"for whatever reason, we began to feel more comfortable first with sex pure and simple, then with homosexuality and now with androgyny"
That was then and this is now, as they say. Clearly, some people thought that the culture wars over sex was over, even as it was just beginning. So, I wonder: what happened?
