Last night at Stella McCartney’s pre-fall presentation, held at the Americas Society Park Avenue townhouse, models stood about in color-blocked outfits while artists painted their likenesses on canvases nearby. Hanne Gaby Odiele looked content, lounging on a chaise as her portrait was done. “The shoes are actually a little small for me, so I was really happy to sit down,” she said, sipping Champagne and taking a tiny grilled cheese from a passing tray. Other models, wearing smart glasses from McCartney’s new eyewear collection, played Scrabble beside a candle-filled fireplace. Guest Jeff Koons was charmed by the whole scene, which also included a ceiling full of pink mylar balloons, a piano player, and a Champagne pyramid. “I’m not a fashionista,” said the artist, as editors like Anna Wintour, Cathy Horyn, and Robbie Myers assessed the collection. “But I enjoy fashion.” Meanwhile, the Seinfelds discussed white sneakers, McCartney talked about her OBE, and the Chandlers traded earrings.
