The evening before Anya Taylor-Joy attended the opening of Jaeger-LeCoultre’s Reverso Stories exhibition in New York City, she dressed up as the ginger crime-fighting cartoon character, Sam, from Totally Spies!. “We had two options,” she tells me the afternoon following Halloween—which saw the actress, Ivy Getty, and Quincey Jones pulling off a group costume for Getty’s party in NoHo.

“It was either Totally Spies, or different versions of Jennifer Coolidge—with fake lips.” (For the record, Taylor-Joy was a big fan of the anime series when she was younger. “Whilst we were getting ready [for Halloween], we were playing some of the episodes in the background,” she adds.)

But The Menu star’s look at the storied watch label’s November 1 party couldn’t have been more different from her shiny green superhero getup. Joining fellow brand ambᴀssadors Lenny Kravitz and Nicholas Hoult, Taylor-Joy celebrated the unveiling of Jaeger’s show, which highlights the new Hokusai Reverso Watch, along with an installation by the artist Yiyun Kang (who is part of the maison’s Made-of-Makers program) and work by “World’s Best Pastry Chef” Nina Métayer.

Taylor-Joy has been a face of Jaeger-LeCoultre since signing on as an ambᴀssador in 2022. For the cocktail party, she donned a Stella McCartney little black dress with a twist: a super-plunging neckline and ruching that resembled a bustle.
