When the French designer Christian Dior presented his first collection in Paris in 1947, he changed fashion forever. Dior's "New Look" created a striking, romantic vision of femininity, luxury, and grace, making him - and his last name - famous overnight. One woman informed Dior's vision more than any other: his sister, Catherine, a Resistance fighter, concentration camp survivor, and cultivator of rose gardens who inspired Dior's most beloved fragrance, Miss Dior. Yet the story of Catherine's remarkable life - so different from her famous brother's - has never been told, until now.

Drawing on the Dior archives and extensive research, Justine Picardie's Miss Dior is the long-overdue restoration of Catherine Dior's life. The siblings' stories are profoundly intertwined: In Occupied France, as Christian honed his couture skills, Catherine dedicated herself to the Resistance, ultimately being captured by the Gestapo and sent to Ravensbruck, the only Nazi camp solely for women. Seeking to trace Catherine's story as well as her influence on her brother, Picardie traveled to the significant places of Catherine's life, including Les Rhumbs, the Dior family villa with its magnificent gardens; the House of Dior in Paris; and La Colle Noire, Christian's chateâu that he bequeathed to his sister.
