Every summer, the Jazz Age Lawn Party on Governors Island turns back the clock to the Roaring Twenties. Hundreds of people get gussied up for two weekends of daytime fun as they kick up their heels to the vintage sounds of Michael Arenella and His Dreamland Orchestra (which also performs Wednesdays at the Clover Club in Brooklyn). Click through for a look at the fashions and stories of some of the previous years' participants, and dress up for the 2019 edition (June 15–16 and August 24–25).
