The official Fashion’s Night Out 2012 Public Service Announcement has just debuted at FashionsNightOut.com and on the splashy digital screens in New York’s Times Square (among other outlets), and it’s pretty darn fun, we must admit.   Set to the tune of Darren Criss’ original version of Madonna’s “Dress You Up in My Love,” it’s an upbeat preclude to the coming fourth-annual global shopping extravaganza on September 6th.   Produced by Laird+Partners and famed photographer and director Norman Jean Roy, the spot was styled by Vogue contributing editor Kathryn Neale. It highlights the spirit behind FNO in celebrity sound bites from the likes of Justin Bieber (“Who doesn’t want to meet models?”), Olivia Wilde (“What am I gonna wear?”), and Arizona Muse (“I can’t wait!”).   Also showcasing the 2012 FNO collection, benefiting the New York City AIDS Fund in the New York Community Trust, all of the members of its who’s who cast wear official Fashion’s Night Out tees.
