The Gagosian Gallery in Chelsea has mounted a spectacular exhibition of works Picasso did of his muse, Marie-Thérèse, in the 1920s and ’30s. The show feature sketches, drawing, paintings, and sculptures from museums and private collections–which means, not only will these works probably never be seen together again, but some may not be displayed publicly for some time. It’s thrilling to see the works I clumsily copied in art classes in person, to squint at the brushstrokes and palette knife marks. And there are drawings and a film of Marie-Thérèse, which reveals an interest paradox: does the Picasso look like Marie-Thérèse, or does Marie-Thérèse–with her strong, round-yet-linear features and full body–look like a Picasso?

The show is free, and even if you’re not a modern art enthusiast, the show is worth it alone for the knitwear inspiration–the strange-but-appealing color combinations, the stripes and shapes, and the clothes Marie-Thérèse wears in the portraits, from hat to sweaters to striped socks, each more chic than ever. Please, if you live in or near New York, go to this once-in-a-lifetime show.

Free at the Gagosian Gallery, 522 West 21st St. through June 25
