Former fashion editor Natalie Massenet launched the high-end shopping site Net-a-Porter, with a sleek and chic look inspired by the format of a magazine glossy. (And she made a cool $350 million when she sold it a decade later in 2010.) It now draws 2.5 million readers monthly. In another corner of the Internet, Harvard Business School buds Jennifer Hyman and Jennifer Fleiss cofounded Rent the Runway. The site has a super easy interface that allows women to rent high-end designer pieces for a special occasion (or whenever!) at a price they can afford. For making the couture world more accessible online, we choose Massenet, Hyman, Fleiss as cyber-stylemakers.
