The paint from the ‘Louis Vuitton' graffiti was still drying as New York's cool kids flocked to the Soho store last night to celebrate the launch of the latest Stephen Sprouse collection. Models Agyness Deyn (first to be spotted carrying the Speedy bag remember), Chanel Iman and Molly Sims chatted fashion over fierce brightly coloured cocktails with trendsetters Leigh Lezark and Erin Wasson - no doubt noting who'd done the ‘Street Chic' dress code best. But this being Marc Jacobs and Yves Carcelle (Chairman and CEO of Louis Vuitton), there wasn't just one party - but three. Guests moved on to a nearby gallery to check out the opening of the Stephen Sprouse exhibit Rock on Mars before hitting The Bowery Ballroom to let rip. The fash pack entered through a tunnel covered in neon pink graffiti to a venue transformed into a world of spray-paint and day-glo in homage to the late Stephen Sprouse. Agy and co were glued to the 66 vintage television sets that played clips of his runway shows and films, before hitting the dancefloor for a special performance by Sprouse's personal friend Debbie Harry. Hmm... somehow we think there will be some sore heads in New York this morning.
