From The Hidden Passion of Katharine Hepburn:
In her senior year at the exclusive Bryn Mawr college, she became involved with an amateur photographer called Ludlow Ogden Smith, for whom she agreed to pose for pictures.Everybody is, Kate, every body is.
“He wondered how I’d feel about posing semi-nude,” she recalled. “Why do things halfway?” I answered boldly. I was very proud of my body and considered myself terribly attractive. My breasts were small, but very good ones. I was accustomed to nudity in our home — not just my father’s, but everyone else, too — so taking naked pictures seemed great fun. When I saw the photos, I was thrilled: I was more beautiful without my clothes than with them.”
