This time last year, Mary-Kate and Ashley Olsen were gearing up to serve cocktails to excited fans at Barneys New York for the first-ever Fashion’s Night Out, unofficially the biggest shopping event of the year, complete with special discounts, cocktails and celebrity appearances. And—as you may have heard by now—the second annual fashion-fest is happening tomorrow night! With the dizzying number of events (check out fashionsnightout.com for the complete list), it’s not going to be easy deciding where to go, especially with all of the star-studded events happening in N.Y.C.  If you’re planning to shop the night away, why not do it alongside your favorite celebrities? Check out a list of star appearances for Fashion’s Night Out after the jump.
