To celebrate the second annual action-packed Fashion's Night Out and the debut of the Spring 2011 collections, QVC is launching its first-ever New York pop-up shop-slash-broadcasting studio at the storied Rockefeller Center.

Opening to the public at 6pm during Fashion's Night Out on Sept. 10, the retail giant will give fans a peek at a three-hour live broadcast dubbed "Fashion's Night Out -- Live From New York," televised on QVC -- which previously aired a Super Saturday show -- at 9pm ET.

During the taping, two highly anticipated QVC lines will launch: K-DASH by Kardashian and Janie Bryant MOD, the '60s-style collection from the award-winning costume designer of "Mad Men."

The evening will also feature appearances by QVC designers including Isaac Mizrahi, Melania Trump, Marc Bouwer, Mara Hoffman, and Pamela Dennis, who will show off goods from their Fall 2010 collections.

Besides the temporary pop-up shop, QVC is creating original fashion-themed programming during New York Fashion Week.

On Sept. 11 and 15 at 10pm ET, the network will broadcast "Live from Mercedes-Benz Fashion Week" straight from Rockefeller Center. During the live show, superstar stylist Rachel Zoe is scheduled to stop by and showcase her newest hot hippie collection and Julie Chaiken will reveal items from her Anonymity by Julie Chaiken line for the first time.
