Under Dior gray skies and a canopy of cyclamens, Jonathan Anderson staged his first couture show for the house with Rihanna, Jennifer Lawrence and Anya Taylor-Joy in the front row.

The trio made late entrances, with Lawrence jetting straight to her seat upon arrival.

Even though she’s a Dior regular, it was Monica Barbaro’s first couture show for the house.

She’s become friends with Anderson as he did the costumes for her upcoming film “Artificial,” costarring Andrew Garfield.

“It was such an interesting process because … the characters are people who you know are still alive and had these monumental things occur only a few years ago.”

Without divulging the plot, Barbaro said working on the process of costuming with Anderson was inspirational. The characters have gone through something “monumental” a few years back, so there are different time periods depicted.

“So it was interesting to see how things become dated so quickly over just a span of a few years or 10 years, to look at, oh yeah, that was the trend of that specific time, and oh yeah, that person is from this part of the world, and so they dressed this way for this period of time, and then they [changed when they] became a Silicon Valley person,” she said.

“Jonathan could spot an item and know exactly what brand had created it when, which is a great skill to have as a costumer. And then, also just his ability to understand shape and the body — he’s a true designer as well,” she added. “It was just a really interesting collaboration.”

Speaking of trends a decade ago, a trend that is popular now on TikTok, what does she remember about her 2016 style? “Probably a lot of sweatpants and over-tweezing my eyebrows.”

Clad in one of Anderson’s first couture looks, she has come a long way.

“Artificial” is directed by Luca Guadagnino for Amazon-MGM Studios, and Amazon founder and executive chairman Jeff Bezos was in the house with his new bride, Lauren Sánchez Bezos.

“I was just happy to be invited. This is a really exciting day. It’s like a dream,” said Parker Posey. She hugged “White Lotus” creator Mike White. “We always get to go to the most exciting places together.” The two filmed together in Thailand last year.

She framed her Dior trench look with pleated pannier hips as a “very chic detective” look. The Marie-Antoinette-esque silhouette inspired her to visit Versailles the day before the show.

Posey just wrapped Martin McDonagh’s “Wild Horse Nine,” costarring Sam Rockwell and John Malkovich, which will premiere in the spring.

The shoot took place on Easter Island, which she called “magical.”

“You’re in the middle of nowhere, but everywhere you look is sky. Everything is ancient. There are no buildings, the air was incredible,” she said. She went cave diving and attended a Mass with Catholic missionaries, among other incredible experiences, she relayed.

“I fell in love with it. I love faraway places,” she said. The actress said this is an exciting time in fashion with so many new designer changes bringing in new energy. Despite navigating the near-dark room for minutes to find her seat, she promptly left to go find artist Justin Vivian Bond, who she heard was in the crowd.

Ruth Wilson was sporting a deep shade of burgundy-red hair, a recently acquired color that she admitted is for reprisal of a role. Could it be “Luther,” costarring Idris Elba, which has been off the air since 2019? She wouldn’t divulge except to say that shooting starts “very soon.”

The actress added that Anderson’s penchant for drama makes him a natural couturier. “He sort of lends himself to couture because he’s big and bold and takes risks, and with his design and tailoring at a house like Dior, he’s going to be amazing.”

Dan Levy, who has been a longtime friend of Anderson’s, praised the designer. “I’m so proud of him and how far he’s come, and this is such a pinnacle of everything that he’s worked so hard for, so it’s unbelievable.”

Levy just wrapped “Big Mistakes” for Netflix, costarring Lori Metcalf. “I’m going to tell you the entire plot, the spoilers and how it ends,” he joked. “It’s a comic thriller, we’re genre-bending.”
