Either way, his wife, Annette de la Renta, brought the curtain down on the evening — which was Oscar’s last dance at the couture, after all.
"That’s the end of the Karl and Oscar show," she declared after sitting quietly all evening. "Time to change partners."
Meanwhile, across town at the Plaza Athénée, Marjorie Gubelmann and Cornelia Guest — young socialites of the old school — mixed a few of their old friends like Deeda Blair and Jimmy Douglas with a few of their new friends like Naomi Campbell and Sean "P. Diddy" Combs.
Never let it be said that the two crowds lacked common ground.
"Oh, show me the ring," cooed Naomi, when she caught site of Gubelmann’s massive canary yellow diamond. (The men in the Gubelmann family have nicknamed it "chow mein," since its shape and size recall a Chinese takeout carton.)
Guest, meanwhile, bonded with Combs over two of their favorite things — caviar and face cream, when she handed him a goodie bag with La Prairie’s Essence of Skin Caviar Eye Complex.
"It’s good for morning puffiness," she told P. Diddy.
And no doubt Combs would need his morning-after remedy after the night he went on to have at Les Bains Douches, where he hosted a hot, sweaty, fabulous party straight out of the Donatella Versace playbook.
"Welcome to the best party of your life," shouted
P. Diddy, when he took to the mic to shout out to his guests. "If you’re here tonight, you’re part of the Sean John family."
Then he let the crowd in on a family secret.
"Next fall," he called out. "Sean John will be coming to Paris." (His New York p.r. said the decision to show the Sean John men’s collection in Paris had not yet been finalized.)
Mick Jagger, the Hilton sisters, Pat McGrath and, of all people, Ivana Trump, jammed to the news.
