By Astrid Wendlandt PARIS (Reuters) – French luxury group Kering is expected to announce as soon as Monday that Belgian designer Anthony Vaccarello will be the new creative director of fashion brand Yves Saint Laurent, a source told Reuters on Friday. Vaccarello will replace Hedi Slimane, whose departure was announced earlier by Kering. Vaccarello, who specializes in designing the “little black dress” and is a fan of asymmetric designs, has been rumored as a potential replacement for Slimane as he will be able to provide more of the same rock chic designs that have proved so popular for the Yves Saint Laurent brand.
