Even Federer felt a quick celebratory dinner wouldn't ruin his game. "I practice all the time," he said. "Instead of going to dinner with my girlfriend tonight, I'm going with 70 people."
It appeared, though, that while guests were happy to celebrate Federer, Wintour was the only one in the room with any skill on the court. "The last time I played tennis was for credit at FIT," said Costa.
"I play — poorly," said Michael Kors with a laugh.
"I play on Wii," said Jimmy Fallon, who with Rachel Weisz represented the Hollywood set. "I can beat most 15-year-olds."
Lauren duPont joked her husband Richard, one of many spouses in attendance for a change, actually bore a resemblance to a tennis player. "He's the scraggly man's Federer," she said.
"Without the strokes," added a friend.
Meanwhile the real thing was busy being introduced to guests like Ivanka Trump and Jared Kushner, Diana Taylor, Jann Wenner and Dylan Lauren. As David Neville approached to pay his respects, Wintour told Federer, "You should wear his clothes." Rag & Bone for Nike, perhaps?
