So your invitation to Derek Lam's show at New York's Mercedez-Benz Fashion Week, which kicks off tomorrow, must have gotten lost in the mail. No problem—watch his and other designers' creations go down the runway online in real time. Zeitbyte Digital Media is offering live streaming of most of the shows taking place in the Tents at Lincoln Center (at www.fashionatlincolncenter.com) and Milk Studios (www.milkmade.com). The company is also working with First Comes Fashion to offer recaps and on-the-scene coverage. You may not be able to rub shoulders with designers at the afterparties but at least this way you can avoid an elbow in the ribs from skinny editors vying for entrance.
