“I want Dior to be the pinnacle,” Jonathan Anderson said before his first collection for the house, a men’s show staged for a relatively small audience, about 600 people, in one of those imposing box-shaped tents. We were all seated on wooden blocks in a gray-washed room, Dior gray, that resembled a museum gallery; on the walls were two paintings by the 18th-century artist Jean Siméon Chardin, on loan from the Louvre and the National Galleries of Scotland, thanks to the clout of LVMH. By “we,” I mean Daniel Craig, Sabrina Carpenter, Josh O’Connor, Robert Pattinson, Roger Federer, Rihanna, and A$AP Rocky; the designers Donatella Versace, Pierpaolo Piccioli, and Silvia Venturini Fendi; and the photographers Juergen Teller and David Sims. “I wouldn’t miss this,” said the English stylist Amanda Harlech, who may have been the chicest woman in the room in her plain summer frock and a babushka that looked like vintage Hermès silk. “I’ve just come from Shropshire,” she said, referring to her home. Harlech was one of Anderson’s earliest supporters.
