Charlotte Perkins Gilman really hated hats.
mosellegreen posted a link to these scans of The Forerunner, a magazine written and published in 1914 by the feminist pioneer Charlotte Perkins Gilman. They're really great. I can't help but be amused, however, by a few of her recurring themes. So far I've counted four polemics against ladies' hats, and three against women who go past their speaking times at conferences. One of them was a poem! Anyway, fantastic stuff.
