"The gist of the article is that U.S. women were browbeaten into shaving underarm hair by a sustained marketing assault that began in 1915. (Leg hair came later.) The aim of what Hope calls the Great Underarm Campaign was to inform American womanhood of a problem that till then it didn't know it had, namely unsightly underarm hair."

"In July of 1915, the first Gillette razor for women came on the market.
