Hundreds of retailers participated in Fashion's Night Out on Thursday night. And even if you hit two or three stores on your tour de fashion, there's no way you could be everywhere at once (unless you were Anna Wintour, whose poor driver must have had some sort of voodoo or witchcraft going for him in order to beat all that traffic). That's why we pooled 137 of the best pictures from the night for you to relive all the excitement. Check out Ashley and Mary-Kate Olsen shaking up cocktails at Barneys New York, Zac Posen hand-painting clothes in Bergdorf Goodman's windows, Taylor Momsen rocking out for Teen Vogue, Kenneth Cole jamming with Matisyahu, Sarah Jessica Parker singing with Oscar de la Renta and Barbara Walters, and Kate Hudson signing autographs at Stella McCartney — all these moments and more in our definitive Fashion's Night Out slideshow.
