If only every party had an espresso martini-fueled Bill Murray sashaying away underneath a disco ball before entrees. ​​

Perhaps the secret then is having Sofia Coppola at the helm, as she was Wednesday evening at the Doubles Club for a dinner thrown with Chanel to celebrate her second book, “Chanel Haute Couture.” 

The coolest girl on TikTok — that would be Romy Mars, Coppola’s 18-year-old daughter — and her younger sister Cosima imitated red carpet photographers as their mother posed for photos. 

“Yes Sofia! Over the shoulder!” they called out at her. 

Romy hung out with Gracie Abrams, while Kirsten Dunst caught up with Nicole Kidman’s model daughter, Sunday Rose Kidman Urban. Elsewhere, Lauren Sanchez was followed around by a bodyguard, Karen Elson and her daughter Scarlett White posed, and Iman and stylist Jason Bolden were deep in a laughing fit. 

Other guests included Jon Hamm, Louisa Jacobson, Abbey Lee, Havana Rose Liu, Quannah Chasinghorse and Chase Sui Wonders.

Coppola was recently back from the Venice Film Festival, where she premiered her documentary on close friend Marc Jacobs. The “Chanel Haute Couture” book was in the works for over a year, and features exclusive photographs of Chanel clients wearing designs, as well as fashion photographs, never before seen sketches, runway images and more. 

“I’m really thrilled that we got many images that we loved,” Coppola said, adding that it was quite the tall order to edit down all the imagery. 

“The book wasn’t supposed to be so big. We kept adding things and I really wanted to have elements from films and fashion and people wearing it in real life. So I really wanted to have the whole picture.”

Coppola interned with Chanel in the summer of 1986, and her youngest Cosima followed in her footsteps by interning with the house this summer. 

“I was so excited for her. It’s amazing to get to share that and yeah, it’s just fun,” Coppola said. 

“It was funny because there’s this transition with Matthieu [Blazy, Chanel’s new creative director]  coming and we’re all so curious, so we were like, ‘what’s happening there?’ I feel she knows more than all of us.”

Jell-O shots were passed around on likely the nicest silver tray a Jell-O shot has ever laid rest on, which turned out to be a hit with guests. Murray, dressed in a tech-bro zip-up vest, opted for an espresso martini, which he sipped before reluctantly posing for photos. Sanchez worked the room’s Condé Nast crowd, chatting with Vogue’s talent booker Sergio Kletnoy and new Vanity Fair editor Mark Guiducci. 

By 9 p.m., Murray had finished his turn on the dance floor, caviar was being spooned onto potato chips by guests, main courses were nowhere to be seen but the crowd was in no hurry to call it a night.
