At six feet tall, Hemingway experienced success as a model, including a million-dollar contract for Fabergé as the spokesmodel for Babe perfume in the 1970s. This was the first million-dollar contract ever awarded to a fashion model. She also appeared on the covers of "Cosmopolitan", "Elle", "Harper's Bazaar", and "Vogue", as well as on the June 16, 1975, cover of "TIME", which dubbed her one of the "new beauties". The September 1, 1975, cover issue of "Vogue" called Hemingway "New York's New Supermodel".
