Mary-Kate Olsen and Ashley Olsen have already taken the fashion world by storm with their designs, and now the duo is tackling the beauty arena with a new fragrance deal. Mary-Kate and Ashley will debut an Elizabeth and James-branded scent this March at Sephora. "We look forward to bringing the modern perspective and fashion philosophy of Elizabeth and James designers Mary-Kate and Ashley Olsen to life with this prestige fragrance," Michael McGeever of Sephora Originals, told WWD. This isn't the Olsen's first foray into beauty, however. Previously they orchestrated beauty launches for Walmart including fragrances and body sprays. But while those were aimed at a more youthful audience, this Elizabeth and James collaboration is sure to be all grown up. This announcement comes after their stellar Spring 2013 showing at New York Fashion Week, and it will be interesting to see how they translate their casual-chic design aesthetic into aromatic notes.
