Paris-born, San Diego-raised Julie de Libran left her position as womenswear studio director of Louis Vuitton in January when the Marc Jacobs team departed. Rumor had it, she was on the list of contenders to replace Jacobs, which made sense, as she was Marc's right hand and largely considered Louis Vuitton's "best kept secret." Instead, she has been named artistic director of Parisian knitwear brand, Sonia Rykiel, effective Monday morning. She'll work from Rykiel's Boulevard Saint Germain atelier, and make her debut during the Spring 2015 collections at Paris Fashion Week in September. De Libran, 42, who has also done stints at Dior, Prada, Versace, Gianfranco Ferré, and Jean-Charles de Castelbajac, will replace Geraldo da Conceicao, who spent five seasons at the helm of Rykiel, after working at Louis Vuitton. De Libran will also keep her super-under-the-radar venture, a small, couture-ish line of made-to-order clothes, that she has been running under her own name since March 2014.
