There was plenty to chew on from the Vogue World press conference in Paris back in February: The Place Vendôme coup, the buy-in of both LVMH and the French government, the sheer magnitude of staging such an event in the lead-up to this summer’s Olympics. Walking out of the Ritz that night, however, all I could think about was the casual conversation I’d witnessed during arrivals between Sidney Toledano—the former C.E.O. of Dior, former head of the LVMH Fashion Group, and current head of the Chambre Syndicale de la Haute Couture—and his long-ago designer, John Galliano. The Maison Margiela creative director was seated on a curved-back sofa with his boyfriend, Alexis Roche, facing out into the gilded Salon Marie-Louise.
