Pink Chanel suit of Jacqueline Kennedy
Jacqueline Bouvier Kennedy was wearing a pink suit that was styled in the fashion of Chanel when her husband, U.S. president John F. Kennedy, was assassinated in Dallas, Texas, on November 22, 1963. She insisted on wearing the suit, stained with his blood, during the swearing-in of Lyndon B. Johnson that afternoon and for the flight back to Washington, D.C. Jacqueline Kennedy was a fashion icon, and the suit is the most referenced and revisited among her clothing items.
