It’s been several seasons since Balmain’s Christophe Decarnin sounded the rallying cry for the Eighties revival that has taken over a good part of fashion. And for fall, the sexy excess continued in an abundance of crystals, sequins, studs and, obviously, shoulders. He co-opted the last days of disco in flashy T-shirts and silk parachute pants mixed with his signature blazers and super-short dresses, some trailing black silk trains.

Yes, these clothes will still rock on the right girl. But even Decarnin’s riff on the Rue Cambon — quilted black leather dresses trimmed with chains — couldn’t hide the fact that, ultimately, this collection was more of the same, and he needs to move on. As king of the nightlife-loving crowd, Decarnin should know that, no matter how fun the party, you never want to be the last to leave.
