Cannes’ red carpet can be as kind as it is cruel when it comes to fashion. For 12 days, major Hollywood actresses such as Marion Cotillard, Emily Blunt, Naomi Watts and Sienna Miller graced the film festival’s red carpet in clothes designed by the world’s greatest. Yet while the best looks come to define the festival, there’s almost as much interest in who got it wrong. It was not Cotillard’s strongest year in the fashion parade — but the Dior brand ambassador fared well in a blue-and-rose truncated minidress from Dior’s haute couture spring-summer 2015 collection at the premiere of director Justin Kurzel’s “Macbeth.” She sparkled alongside co-star Michael Fassbender, thanks to the outfit’s myriad of embroidered pailettes and jewels. The Oscar-winner, who’s known for her fashion-forward style, bucked the trend for classical va-va-voom and voluminous dresses that were popular this year at Cannes.
