Frédéric Tcheng’s masterful documentary enters the storied world of the House of Christian Dior, with a privileged, behind-the-scenes look at the creation of Raf Simons’ first Dior Haute Couture collection as artistic director. Beautifully melding the everyday, pressure-filled components of fashion with a mysterious and elegant reverence for the history of this iconic brand, Tcheng’s colorful homage to the seamstresses of the atelier is nothing short of magical.
