Another day, another dozen Fashion Week parties. Last night (and, well, very early this morning) brought Barneys’ launch party for their new Lou Doillon ad campaign, attended by Max Snow, Anna Dello Russo, and Doillon herself, who performed for guests. Farther uptown, Leandra Medine held a book signing for her new memoir, and Town & Country hosted well-dressed gents like Jason Wu and Jesse Metcalfe for their Men of Measure event at Bergdorf Goodman. Finally, hardcore night owls like Lil’ Kim and Jessica White congregated at the Box to celebrate the release of Coleman’s new single.
