Daily Mail: Two of the world’s most influential fashion mavens — Anna Wintour and Natalie Massenet — could be set to lock horns over Conde Nast’s new shopping website. Wintour, the 65-year-old editor of American Vogue, is turning Conde Nast-owned Style.com into a designer e-commerce site, where readers of her style bible can snap up garments featured in its glossy pages. This pits her in direct competition with Massenet, the 49-year-old businesswoman who founded Net-a-Porter, perhaps the most powerful luxury online boutique in the world.
