Kate Middleton and Carey Mulligan twinned in matching tweed button-down dresses by Erdem. Both women pulled off the look with aplomb: Carey opted for pared-down makeup and an undone bob at the Harper’s Bazaar Women of the Year Award in London, while Kate worked the look with an immaculate blow-dry at the opening of the V&A Photography Centre.
