HOW TO SUCCEED: Rules to getting ahead in the fashion business are outlined by the biggest influencers in the industry in “The Teen Vogue Handbook: An Insider’s Guide to Careers in Fashion.” But on Tuesday night at the Gramercy Park Hotel’s Rose Bar, fashion insiders remembered ways they almost ended their careers before they could flourish. “There was a time where I put all of the furs on a Vogue shoot with Deborah Turbeville into the water, and the entire fur industry wanted to sue me,” admitted Vera Wang. “Another time we ruined a Frank Stella painting…we were shooting at night and I remember watching a model jumping up and down in front of a work of art that fell apart. It’s hard to put a number on it, but that work of art was worth a quarter of a million 35 years ago. That’s probably $3 billion now.”

Rachel Roy’s gaffe came while interning at public relations firm KCD: “I was to man the Marc by Marc Jacobs store, and I didn’t recognize Marc’s boyfriend and I didn’t let him in.” Amanda Brooks remembered putting the wrong gallery address on event catalogues while working for Larry Gagosian. “That was a pretty big f--- up. Needless to say I got told off. Big time. Big. Time. Doors slammed. Swear words were said.”

J. Crew creative director Jenna Lyons remembered when gossiping in the workplace earned her a scolding from then-coworker Josh Patner, who later cofounded Tuleh and is now a writer. “I did something really stupid with Josh where I talked about something with a friend and it got back to him. And he pulled me into a closet and said, ‘You dumb little girl!’ Gossiping wasn’t appropriate.” Some attendees at Tuesday’s event showed up with youngsters, who are the book’s prime targets, including Patrick Demarchelier and his sons, Victor and Arthur; Arthur Elgort and his daughter; Yvonne Force Villareal and her son, and Helen and Tim Schifter and their daughter Storey, who mingled with Chanel Iman, Thakoon Panichgul, Steven Kolb and Justin Giunta.
