Doesn't prohibit it, doesn't mandate it either. Just as an opinion i would put it in the category of "it's not a sin but may be unwise".
I have to say, when i saw the thread title i thought this was gonna be one of those "women were put here to be beautiful ornaments and why don't all women discomfort/inconvenience/torture themselves to be more appealing" threads. I am SO happy to have been proven wrong.
I found this article a while ago when i was debating someone on a different forum about this topic.
INSH | Ancient Egyptians gave us the pyramids, but they also started a trend in the midst of all that massive stone block-stacking: completely hairless women for aesthetic reasons only, from the tops of their heads to the tips of their toes and all points in between.

Since this is the religion subforum im gonna say that a pastor i read often says that egypt represents worldliness, so the fact that egypt started the trend is not a good sign.
Aside from the religious factor, i have noticed that the ww2/post ww2 period is when a lot of the social engineering agendas we see today kicked off, and promoting shaving legs is no exception.
