While New York Fashion Week was in full swing on the east coast, over in Los Angeles, the scene was far more tranquil. On Tuesday evening, Chloé and the Museum of Contemporary Art, Los Angeles, gathered a few friends and collaborators for an intimate dinner, private tour of the museum (think Night at the Museum, but more fashion), and small performance. Among the attendees were a clutch of art world patrons, artists, and art scions (Ed Ruscha's daughter Sonny, MOCA trustee Carolyn Powers) as well as musician Zella Day — the performer of the night, in an edgy leather Chloé ensemble, and guest of honor Kate Bosworth, also in head-to-toe Chloé. Amid a night hobnobbing with the art world, Bosworth still had time to take in some Rothko, complete with a minor art history lesson.

Who: Kate Bosworth.

When: Tuesday, September 13.

Where: A private dinner, tour, and concert celebrating Chloé and the Museum of Contemporary Art, Los Angeles.

What: A Chloé white silk turtleneck with pleats and high-waisted black trouser pants with black pumps.

Why: Miss Bosworth is a well-established fan of Clare Waight Keller's designs over at Chloé. Just one night after the MOCA dinner, she sported a chambray Chloé blouse for the pilgrimage to Beyoncé's Lemonade tour. She shows off the brand's versatility — from night at the museum to night on the town — with the two looks. For the MOCA dinner, Bosworth embraces what we're calling an art world ensemble: posh, monochromatic, a little severe, a little androgynous, but also quite classically feminine in the details. She's basically gone undercover as a gallerist-slash-curator-slash-art world patron. (Is that really Kate Bosworth there?) Topping it all off, a bright mulberry lip and a few strategically tousled flyaways pulled out of a center-parted up-do: a tiny nod to California cool with her perfectly unkempt, sunkissed hair.
