The Heart Truth’s annual Red Collection Fashion Show helped kick off New York Fashion Week last night, with more than 20 stars—including Victoria Justice (in Oscar de la Renta), AnnaSophia Robb (in Alice + Olivia), and Colbie Caillat (in Nicole Miller)—channeled their inner models to strut down the runway at Lincoln Center wearing stunning red dresses by top designers made exclusively for the show. Combining fashion and famous faces to help raise awareness for heart disease, the event motivates them to take action to reduce their risk. Standout moments from the night? Lindsey Vonn raising her crutches triumphantly at the end of the runway, Joan Jett’s decision to forgo a dress and opt for a Catherine Malandrino jumpsuit, and the dance party finale that had all the celebrity-turned-models goofily dancing in their gowns to conclude the show.
