The party has officially begun. Today is the first day of the Cannes Film Festival, which in case you don't know, is kicking off with the premiere of the Great Gatsby. You might have noticed that we're borderline obsessed with all things Gatsby here at Grazia HQ, so we can not WAIT for tonight's premiere.
Carey and Leo are the first to be photographed in front of the sparkling blue water on the Riviera, as the Great Gatsby photocall took place this lunchtime. Ms Mulligan, who seems to be allergic to embellishment, frothy frocks and colour, continued her minimal-chic streak, in a strapless black Balenciaga jumpsuit with delicate beading and a simple bow on top of the circular bodice.

This is the second time she has worn Balenciaga by Alexander Wang's Fall 2013 collection, as she wore a black cut out Balenciaga frock to the Met Gala. She paired the jumpsuit with simple t bar heels and a pair of Tiffany & Co diamond earrings. While Isla Fisher looked oh so pretty in a white lace simple shift dress, with tumbling fiery locks and a killer, bright red lippie.
Tonight's premiere of Gatsby will kick off the 12 day film festival, so what will Carey wear for tonight's extravagant bash? We're thinking she'll steer clear of brights and flapper-esque beading - perhaps structured Victoria Beckham? Or a chic Lanvin frock? Or perhaps she'll stick to Miuccia Prada who designed the costumes for the film? Ms Cara D has also been spotted arriving in Cannes with a big Burberry clothes bag.
While we count down the hours till the premiere, take a look at Carey's Gatsby promo wardrobe so far and then if you're craving even more Cannes fashion check out our pick of the best frocks from the Riviera ever.
