For a week and a half, the Cannes Film Festival gathers celebrities and influencers in the South of France. With red carpets staged adjacent to the Côte d’Azur and parties taking place on docked megayachts, the fashion’s fit for the glamorous event. This year’s extravaganza, the 69th annual, which kicks off on Wednesday, will see the likes of Blake Lively, who’s in Woody Allen’s Café Society alongside Kristen Stewart and Steve Carrell, Julia Roberts and George Clooney promoting Money Monster, Ryan Gosling and Russell Crowe debuting The Nice Guys, and so many more stars vying for the prestigious Palme d’Or. But who will win best dressed? That’s the really important question.
