CALVIN’S CLAN: Designers across Manhattan have been working for weeks to secure talent and resources for Fashion’s Night Out. Champagne’s being ordered, celebrities are being booked and gifts-with-purchase are being produced. Calvin Klein has nailed down its plans: a performance by CK One model Jamie Burke and his band, burke; a silent auction featuring works by Ross Bleckner, Steven Klein and Kenny Scharf, and appearances by Michelle Monaghan and Olympic fencer Jason Rogers. Creative directors Francisco Costa and Italo Zucchelli also will be on hand to sign Fashion’s Night Out T-shirts. Should all this fanfare motivate shoppers to spend over $1,000, they will receive a $250 Calvin Klein Collection gift card.
