Every year chocoholics gather in France for the Salon du Chocolat—the world’s largest chocolate event. A highlight of the five-day convention is the chocolate fashion show, which features clothes good enough to eat. Among other things, models stomp down the runway in chocolate kimonos, truffle leggings and chocolate and marzipan shawls. Fearing their creations will melt under the stage lights, designers don’t dress their models until moments before the show.
