The days leading up to the annual Costume Institute fundraiser, better known as the Met Gala, have become as busy as any city’s fashion week, with dozens of parties, dinners, and activations surrounding the main event. This year, the timing coincided with Frieze New York, one of the lesser art fairs but still an important moment for fashion brands eager to court high-spending collectors. On Thursday, alone, there were dinners celebrating Alaïa, the latest issue of 10 Magazine, and Sofia Coppola’s collaboration with skincare brand Augustinus Bader. On Friday, private equity off-hours brand Stone Island fittingly invited friends to Carbone.
