MAGIC HOUR: As fashion show backdrops go, the soaring spire of Château de Chantilly is pretty cinematic. The castle wowed guests on the Valentino couture show Wednesday night, because the golden hour sunset forged a magical light.

“They understand spectacle,” said actor and playwright Jeremy O. Harris. ”Also certainly one of Moliere’s first plays premiered here, so there’s some good theater history and I’m very enthusiastic about that.”

It was his first time attending a Valentino show and meeting designer Pierpaolo Piccioli. He chosen a crisp white coat over a sleek black suit for a monochrome look that suited the breezy evening. The “Emily in Paris” star was also catching up with pals. “Little Women” star Florence Pugh, and YouTuber Emma Chamberlain were on the guest list.

“I’m having some good times, chilling with Florence, seeing Emma. There’s numerous good people around,” Harris said of the guests that made the trek to the destination-but-not-a-destination show two hours outside of Paris.

If Valentino set the stage, Pugh knew the way to milk it. She was wearing a sheer lavender gown with a flowing train, and rejoiced flipping, flaring and fluffing it within the sunset light for some dramatic pics.

Baz Luhrmann was also directing some fashion scenes, helping guest adjust their outfits. The “Elvis” director has turn out to be a front row regular in recent seasons, and praised the show for its execution.

“It was an exquisite piece of opera really, it was so exquisitely beautiful,” he said. “It was an enormous risk to bring everyone out here to be within the clutches of the weather, which could have gone badly, but then to have probably the most perfect light. Then in fact he had the garments.”

The Oscar nominee played coy when asked if he plans to direct a fashion film. “Such an interesting query,” he mused, before deflecting: “Is that the sound of the party?”

Naomie Ackie said she’s been on holiday since her trip to the Cannes Film festival in May, where she won the Chopard Trophée award. The “Whitney Houston” actress has a history with the home.

“My first couture fashion show was Valentino and it was an enormous moment for me, because I’ve all the time loved couture and had such huge respect for it and to give you the chance to go to Valentino was an enormous deal for me,” she said.

“I feel I’ve been too nervous to really look where I’m because I’ve been just attempting to deal with looking nice,” she said of the striking setting. The actress was wearing a brief suit jacket and tie, with a full length skirt.

After a summer of “chilling out,” Ackie will get behind the keyboard to complete writing her first screenplay. “It’s really hard, like really, really hard. It’s harder than I believed it will be,” she said of the method. “So fingers crossed, wish me luck.”

Chamberlain was carrying two Valentino V handbags that coordinated along with her pink outfit. “I would like numerous space however the tiny bag look is so good, so that is like every part you would like and more,” she said. She keeps her phone and camera within the larger bag, and her lipstick within the smaller one.

“The setting is so elegant and romantic and exquisite, and all of the looks matched that energy,” Chamberlain added of the show.

“Crash Landing on You” actress Son Ye-jin made her approach to France for her first fashion show appearance since having a baby last fall, with other guests including “And Just Like That” star Nicole Ari Parker, singer Raye and rapper Saint Jhn.

After the show, guests made their approach to the castle’s gardens. Pugh removed her shoes and carried her train as she frolicked with mom Deborah Mackin, while Ackie and Harris danced the night away.
