Pierre Balmain launched his eponymous label in 1945 after working alongside Givenchy and Dior in Paris, turning Balmain into a label of lavish femininity that took over royalty's sartorial treasures. With 25-year-old Olivier Rousteing taking the helm in 2011, Balmain's legacy continues as a 21st-century icon of bold, unapologetic design.
