When I was a fashion journalism student, we were encouraged to “blag” our way into invite-only catwalk shows, using whatever cunning wiles we could. Flirting with doormen, or pretending we were Voguettes, was par for the course. These days, things are more sophisticated. Last week, Vermont students, Remy Renzullo and Becca Shumlin, hacked into seating plans for hot-ticket shows at New York Fashion Week, which begins tomorrow and kicks off a month of catwalk collections over four fashion capitals. Positioning themselves in prime spots usually reserved for fashion glitterati at shows including Alexander Wang and Preen, the feisty pair were soon discovered and struck off the guest lists. You have to admire their bottle. For undeterred bluffers, here is our low-down on the shows to see, names to drop and disguises to don for each city.
