Editor-in-chief of Harper's Bazaar and Town & Country, Justine Picardie, has announced that she will be leaving the publications to focus on her new book Miss Dior. 

Justine said on her Instagram: "After more than seven truly fulfilling years at Hearst as the editor-in-chief of Harper’s Bazaar and Town & Country, I have decided to step aside from these roles, in order to write my new book, Miss Dior, which will be published in the UK by Faber Books and in the US by FSG Books. "I feel immensely privileged to have edited two of the greatest titles in the world. It has been an honour to cherish their remarkable heritage, and a joy to nurture new creative talent, as well as building a team of brilliant and beloved colleagues. I’ll be remaining the role for the next few months - and attending the coming season of shows - so there will be time to ensure a smooth transition and many fond farewells. I’m also looking forward to the future when I’ll continue to write and contribute to Harper's Bazaar and Town & Country - while embarking on the next great adventure of life."
