A lesson in minimalism was delivered by Dianna Agron at the Paris premiere of The Family when she demonstrated the LBD's timeless elegance in a crisp Valentino design. Paired with sleek Louis Vuitton pumps and a handful of garden-inspired rings, this natural beauty was an instant classic. But Dianna's wasn't the only top look of the week! We saw bright dresses from Carey Mulligan (in Dior) and Lupita Nyong'o (in Miu Miu), while three sparkling stars shared Salvatore Ferragamo's red carpet.
