The film festival, which took place over almost two weeks, brought lots of fashion to the French Riviera.There has been a lot of head-turning fashion on the French Riviera lately. Though some of it was spotted on guests at the Monaco Grand Prix (hello Bad Bunny in torso-hugging Jean Paul Gaultier), much of it came from the Cannes Film Festival, which ended on Saturday.As one might expect from a pack of A-list celebrities attending a star-studded festival in a particularly glamorous location, there were lots of gowns and tuxedos. But in contrast to the Oscars or other awards ceremonies, there were many daytime events at Cannes, which gave many festival attendees repeated chances to dress up and take style risks — some of which were more successful than others.There were a lot of outfits that caught our attention during the almost two-week festival, including Jennifer Lawrence’s red Dior gown and flip-flops (most comfortable!); Naomi Campbell’s Valentino dress and flowing pink feathered cape (most ethereal!); and the nearly identical tan linen blazers that David Zaslav, a media executive, and Graydon Carter, an editor, wore as co-hosts of a party for the Warner Bros. movie studio (most coordinated!).But the 20 looks on this list stood out more than most. Some were unexpected, while others were flawless. All, importantly, drew strong opinions.Cool blue.Mohammed Badra/EPA, via ShutterstockHelen Mirren: Most Blue Crush!To match her cornflower-blue Del Core gown (and her nails), the actress wore blue streaks in her wavy silver hair, the colors of which recalled a frothing ocean.This skirt seemed made for shimmying. via Paco RabanneElle Fanning: Most Antique Silverware!The actress’s metallic Paco Rabanne dress was suspended by what looked suspiciously like a piece of cutlery and had a skirt that looked as though it could cut someone who came too close.You can practically hear the tiger’s roar.Vittorio Zunino Celotto/Getty ImagesFan Bingbing: Most Scenic!Printed on the actress’s Christopher Bu gown was a design featuring a roaring tiger in a bamboo forest that extended onto the dress’s train.A commanding presence.Andreas Rentz/Getty ImagesViola Davis: Most Volume!A towering Afro and a colossal ostrich-feather stole punched up the actress’s otherwise simple Valentino dress.Free the shoulder!
