FRONT-ROW JEWELS: Could Audrey Marnay be taking up the jewelry-designing mantle again? The model-turned-actress, who’s designed jewelry in the past, hinted at a project in the works with Gaia Repossi as the two sat in Nina Ricci’s front row Thursday. Marnay is on the promotional circuit for a French tragedy, “The Man Who Saved the World,” in which she plays the love interest. “I’m the happiness in the movie,” she beamed. Dolores Chaplin, meanwhile, talked up her sister Carmen’s directorial debut, called “Bombay Nights,” due to film in India. “I’m playing Holy Golightly. It’s ‘Breakfast at Tiffany’s’ in Bollywood,” she said. French actress Raphaëlle Agogué said she’s agonizing over what to wear for the premiere of “La Rafle,” or ‘The Roundup,” on Monday. “I’m torn between a black leather Hermès number or a pink float-y Alberta Ferretti,” she said.
