Midsummer Night Swing: The Hot Sardines

Retro partyers Gemini & Scorpio hijack—or, rather, collaborate with—Lincoln Center's outdoor dance bashes in honor of Bastille Day. The Hot Sardines and accordion player Mira Stroika will perform a collection of chansons. Grab a beret or Marie Antoinette wig for the French-themed costume contest. The party continues into the wee hours at Iguana New York (240 W 54th St between Broadway and Eighth Ave) with electroswing tunes and $5 mojitos and margaritas.
