One of the best things about a big red carpet event like the Cannes Film Festival is the possibility that we might see something from the elusive and exclusive Gucci Premiere label, which consists of Frida Giannini's couture creations for the rich and famous.

As wife of Francois-Henri Pinault, CEO of PPR (which owns Gucci) Salma Hayek has VIP access to the range, and always pulls it out of the bag at Cannes in something amazing. This year has been no exception, as she attended the Once Upon A Time In America Gucci Film Foundation premiere in a luxurious beaded and bejewelled creation with an ombre fishtail.

But she was given some serious competition when it comes to the 'queen of Gucci' title from Jessica Chastain, who attended the Lawless premiere in a stunning pink chiffon and sequin dress. We're tempted to say this is the best Jessica has ever looked, trumping even that Alexander McQueen Oscars dress.
