Even if you didn’t score Fashion Week tickets, you can still mingle with the beautiful ones at the second annual Fashion’s Night Out on Friday, Sept. 10. Barneys packs the most bang for your buck (especially since it’s free!): the Olsen and Mulleavy sisters, Proenza Schouler, the Rag & Bone boys, Daphne Guinness and many more will gather for karaoke, Ping-Pong and musical chairs (Madison Avenue and 61st Street, 6 p.m. to 11 p.m.).
KIKI DE MONTPARNASSE offers, among other things, an “Erotic Photo Booth” (79 Greene Street, free).
CHANEL is giving away free manicures in limited-edition shades (139 Greene Street).
OPENING CEREMONY will create a French-style flea market in the lobby of Ace Hotel (1190-1192 Broadway, free).
