Much to the delight of champagne-sipping guests and surprised commuters, Moncler Grenoble staged a flash mob-style fashion show in the middle of Grand Central Station for its 2011 Fall Collection. The French fashion house, celebrated for it's exquisite puffy jackets, pulled off a major traffic-stopping dance number, in the midst of a season it practically owns. Moncler choreographed 160 down- and mitten-clad models to the tunes of Barbra Streisand, the O'Jays and Prince. The mustard, berry and grey collection is sure to brighten anyone's season.
