New York Fashion Week is here and in full swing, peeps. So far, we've scoped celebs in seriously enviable outfits (hellooo, Alexa Chung) and admired many a sleek street style look—but now we're taking you behind-the-scenes. Our week-long series of diaries from fashion insiders kicks off with TRESemmé stylist (the official hair sponsor of Mercedes-Benz Fashion Week) Jeanie Syfu. Jeanie is giving us an exclusive look at her day spent styling the mega-models who rocked the runway at the Marissa Webb Fall '14 show. Join us for the ride!
