Last night if you happened to wander onto the ninth floor of Barneys New York on Madison Avenue, you might have thought that you’d entered a room just moments after school yearbooks had been handed out to a group of particularly well-dressed graduates. Why? Because guests there to celebrate the launch of Vogue’s new book, “The Editor’s Eye,” were clutching all six and a half pounds of it to their chests as they dashed around trying to gather signatures for the opening pages.

Luckily, they had a good pool to choose from: Grace Coddington! Tonne Goodman! Phyllis Posnick! Carlyne Cerf de Dudzeele! Derek Lam! Joseph Altuzarra! In other words: The who’s who of the fashion world, all in one room.

The event was co-hosted by Vogue Fashion Director Tonne Goodman and International Editor at Large Hamish Bowles, who wrote the introduction to the book. Meanwhile, Grace Coddington, the magazine’s famously flame-haired creative director, was one of eight legendary Vogue fashion editors profiled in the book. When asked what the hardest part of the job is, Coddington told us: “Surviving.” As for the most important trait a fashion editor can have? Passion.

Against a soundtrack of tunes by Blondie and Florence + the Machine, Barneys’ own Mark Lee, Daniella Vitale and Tomoko Ogura mingled with Carolyn Murphy, Maria Cornejo, Caroline Trentini, Hilary Rhoda, Erin O’Connor, Frédéric Malle and Patrick Demarchelier, among others, all sipping champagne and devouring caviar by the pound.

We snagged a moment with Demarchelier, whose iconic photographs make several appearances in the book, to ask if he’d had any favorite shoots over the years. His response? “All of them. They were all fantastic.” Flip through the book and you’ll surely agree.
