Day One of Fashion Week was all about the new rising class of models, save for one odd appearance. Richard Chai picked last season's Calvin Klein exclusive, Melissa Tammerjin, to open his show, while Polish heavyweight Jac closed. Moroccan beauty Hind Sahli closed for Jen Kao's spring collection; meanwhile, Sigrid Agren made her first appearance this season opening for Ruffian, and stylish Swede Dorothea Barth Jorgensen closed. For Richie Rich's return to Fashion Week, the flamboyant designer bagged socialite Tinsley Mortimer to open his spring 2011 show. The normally media-loving Mortimer has been unusually under-the-radar as of late, so we'll give her a cookie and hand her yesterday's win. Sorry, models! See all of Thursday's openers and closers in the slideshow ahead.
