Guess who turned up at the party unveiling J.C. Penneys new American Living line of home furnishings and clothing? Chairman-CEO Myron Ullman and CMO Mike Boylson were outshone by Christian Siriano and Chris March, finalists in this season's "Project Runway." The pair was swamped with well-wishers and smiled for TV cameras as they dodged servers bearing trays of teeny tiny hamburgers, mini pigs-in-a-blanket and cole slaw on cucumber slices. The big surprise -- other than the fact that they stayed to watch country band Rascal Flatts -- was that cockatiel-coiffed Christian, who comes off in the Bravo series as rather petulant and, um, fierce, is actually quite gracious in person. So, of course, is good-natured Chris, the one always cited as a fan favorite. When Christian, whose designs tend toward gothic black, was asked how he liked the Polo Ralph Lauren-inspired American Living line, he said it was well designed and well suited for middle America, at which point Chris quipped that Christian might soon be designing for Kmart. As if.
