Mike Potter, creative genius behind the hair and makeup of Hedwig and the Angry Inch, and Aaron McCann celebrated Black Friday without waiting in any lines or rushing for any sales and instead launched their rock-chic cosmetic creation, KO (pronounced Knock Out), at the brand spanking new Gary Graham Boutique in New York City. Guests including Taylor Momsen, Karen O, Matt Sundin, Michelle Buswell, and New York City's "World Famous Bob" popped in to sip bubbly and test out KO's first product, a black or white nail polish that goes on flat and wears into satin.
