The city’s premier shopping fundraiser, Miracle on Madison Avenue, presented by the Madison Avenue Business Improvement District, returns for the 31st year, bringing its inimitable combination of fashion, philanthropy, and holiday cheer to New York’s most fabulous boulevard. First-timers like Stella McCartney, Derek Lam, and Carolina Herrera join longtime participants like Ralph Lauren, Bally, and Bonpoint to donate 20 percent of their sales on Saturday, December 2, from 10 am to 5 pm, to the pediatric programs of the Society of Memorial Sloan Kettering Cancer Center. Plenty of others will get in on the festivities too: carolers in 19th-century costume, the famous MSK Caring Canines therapy dogs, and a society photographer shooting holiday portraits. Here is Gotham’s exclusive look at how to kick off the season in style!
