The scene outside Schiller's Liquor Bar frequently resembles a fashion shoot but yesterday there really was an ad campaign being produced on the corner of Rivington and Norfolk. We're told Banana Republic bought out Schiller's for the day but only shot inside for about an hour. They spent most of the day outside soaking up the sunshine and the LES street life.The model was actress Krysten Ritter of "Confessions of a Shopaholic."
