Calvin, Ralph, Isaac, and Oscar all premiered their spring collections on the last day of Fashion Week. So who were the lucky ladies to open and close for New York's biggest? Mizrahi chose runway fixtures Abbey Lee for his first look and Karmen Pedaru for his last. Casting director Jennifer Starr hired Russian model Anna Selezneva to open for Ralph Lauren, while label face Charlotte di Calypso closed. At Oscar de la Renta, the designer had the label's face, Karlie Kloss, open and close. And last but certainly not least, casting directors Maida Gregori Boina and Rami Fernandes selected rising star Daphne Groeneveld to open Calvin Klein, but it was the brand's signature face, Lara Stone, who closed. With an advertising exclusive to CK for 2010, it only made sense that Stone's first and only appearance this week was for good ol' Calvin. See all of yesterday's openers and closers in the slideshow ahead.
