Jean Paul Gaultier took over the city’s traditional outdoor Forville Market on Friday night to fete his latest collaboration with Piper-Heidsieck with a grand cabaret-themed dinner. Waitresses in old-fashioned knickers and boys in striped T-shirts and berets served cocktails in a market area dotted with stands carrying fresh fruit and veggies before a red velvet curtain swished open to reveal a candlelit banqueting table. During the dinner, guests including Rossy de Palma, Paz Vega and Inès de la Fressange sampled the designer’s cancan-inspired bottle for the Champagne house while Hula-Hoop twirlers and cancan dancers entertained guests. Gaultier said he planned to return to Cannes on May 19 for the premiere of Pedro Almodóvar’s in-competition “The Skin I Live In,” for which he designed some of the costumes. “It’s the third time I’ve worked with him. I love Cannes because it’s so glamorous and unique,” said the designer, who was eschewing alcohol. “I’m on a diet so I’m not drinking alcohol. Even for my birthday cake in April, I couldn’t eat it,” he sighed.
