The biggest story to emerge from Fashion Week doesn’t have anything to do with the designers currently showing in Paris. It’s all about someone who used to show there, but then made like all of your friends and starting chilling in LA: designer Hedi Slimane, whose work at Dior and Saint Laurent completely upended the menswear world, is set to take the helm at Céline, per an announcement from luxury conglomerate LVMH Sunday morning.

“He is one of the most talented designers of our time,” LVMH chairman Bernard Arnault said in a statement. “I have been a great admirer of his work since we collaborated on Dior Homme, which he launched to global critical acclaim in the 2000s. His arrival at Céline reinforces the great ambitions that LVMH has for this Maison.” And those ambitions are indeed great: Slimane will serve as Artistic, Creative and Image Director of Céline, and, per the New York Times, he’ll open a studio in Los Angeles. The picnic basket of titles suggest he’ll have the same power he did at Saint Laurent, if not more, where he executed a head-to-toe rebrand, pivoting toward ultra-shoppable cool-kid looks. (Remember: before Slimane put even the name on a diet, the house was called Yves Saint Laurent.)

In an era where designers carousel in and out of jobs with striking frequency, Slimane has managed to wrest a seemingly unprecedented level of control over the brand. And a Céline men’s line will need that—because Céline hasn’t ever had a menswear line before. (Unless you count the blouse Kanye West wore at Coachella in 2011, which we’re inclined to do.)

But what, exactly, Céline men’s will be remains to be seen. The Céline job has been open since Phoebe Philo left the French label in December Filling her Stan Smiths would be a sizable task for any designer, let alone one with such a markedly different sensibility. Philo’s Céline was strictly a women’s brand, and a genuinely fascinating one at that: Philo’s clothes were all about nonchalance and movement—easy luxury.

Slimane’s clothes are...not that. This, after all, is the guy who invented the skinny suit at Dior, and made the off-duty rock star T-shirt-and-skinny-jeans-and-Chelsea-boots look available to regular dudes. His clothes are skinny—Karl Lagerfeld famously lost 80 pounds because he wanted to fit into Slimane’s Dior designs—and emerge from a relatively shallow pool of mostly rock-and-roll references.

That’s not to splash cold water on the hire, or to call it anything but what it is: incredibly exciting. Hedi Slimane is the reason that you can buy skinny jeans at Old Navy, and the reason every terrible dude in Los Angeles dresses frustratingly well. His return is a big, big deal; the idea of how Slimane will make his mark at a house so closely aligned with another designer (and another sensibility) is enough to make a menswear nerd faint. We’ve already marked our calendars for his first show with Céline in September.

And here's the fun news: the game of fashion musical chairs isn’t anywhere close to over. The men’s positions at Burberry, Versace, and Louis Vuitton all remain open, and the names being tossed around—Virgil Abloh, anybody?—are exciting. But whoever winds up taking those jobs will face suddenly steeper competition, because Hedi Slimane is back, and we’d imagine he means business.
