FEET FIRST: “It’s all about the shoes,” Zoe Cassavetes quipped at the party to celebrate the opening of Sergio Rossi’s new concept store on Rue Saint Honoré here. A director, screenwriter and actress, Cassavetes had chosen to sport a towering pair of the PPR-owned brand’s bright red patent pumps. “I love shoes,” she confided, mentioning in passing that she has finished writing a new film, which she is now trying to get together. “I don’t want to tell you anything else, in case I jinx it,” she said. Italian fashion journalist Giovanna Battaglia turned up in one of creative director Francesco Russo’s latest designs, a pair of Dalmatian-spotted ankle boots with ruffled tops. The store was jam packed and overflowing onto the street with a mix of celebrities and the international fashion set. Sergio Rossi’s president and chief executive officer Christophe Mélard and PPR deputy chief executive officer Alexis Babeaux mingled with the likes of Joséphine de la Baume, Anna Dello Russo and Carine Roitfeld.
