Where’s Ben Stiller when you need him? The Night at the Museum star was no where to be found across a series of late-night parties and galas that popped inside New York City’s most treasured institutions of art, like the Whitney Museum of American Art and the Guggenheim. Fashion’s rat pack , however, stepped out in droves all week long.

Karlie Kloss played co-host at the Whitney’s annual Art Party on Tuesday, when she was joined by—and wore a dress from—designer and fellow co-host Brandon Maxwell. For Kloss, the week didn’t spare any time for a Netflix-and-chill session. She also dazzled in a gilded, deep-V Michael Kors dress at L’Oréal Paris’s Women of Worth celebration in N.Y.C. alongside Eva Longoria and Blake Lively, and later turned to a LBD (a Dior version, nonetheless) at the Guggenheim’s International Gala 2016.

Poppy Delevingne and her stylish squad packed into New York’s Museum of Modern Art on Tuesday for its Chanel-hosted Film Benefit, where the model honored Tom Hanks, who was on hand with wife Rita Wilson. Christy Turlington Burns, Alexa Chung, and Emma Watson were just a few talented stars that cut quite the classic figure in  Chanel that evening.
