In 1946, she was hired as a writer for a new women's magazine, Elle. Two years later, she began writing for the French edition of Vogue, which named her editor-in-chief in 1954, replacing Michel de Brunhoff (brother of Jean de Brunhoff, the author of the Babar children's books). She promoted the careers of up-and-coming designers, notably Emanuel Ungaro and Yves Saint-Laurent.
