The full load of Saturday shows did not deter the people from swinging by Friday night's parties. Peter Brant II and Nick Gruber sang their hearts out at the Chez Andre opening party, where other revelers included Theophilus London, Olivier Zahm, and Karlie Kloss. Rebecca Minkoff held her spring 2013 show's after-party at The Gramercy Park Hotel; Iman feted her new website, Destination Iman; and Carine Roitfeld joined the crowd at the new Emporio Armani flagship's launch. See all these parties and more in our slideshow roundup.
