TIED DOWN: Looks like the Four Seasons is taking the current heat wave seriously. The restaurant recently relaxed its tie requirement for men during lunch and dinner, a standard that Le Bernardin and La Caravelle follow. At lunchtime, men at La Côte Basque and Jean Georges need not bother with a jacket, either. "During the summer months, it gets extremely hot, and people just aren’t wearing ties," explained Julian Niccolini, the Four Seasons’ managing partner, who insisted that come fall, the former dress code will be reinstated. Among the restaurants where the right to loosen up is refused: Le Cirque and Ducasse, where jacket and tie are required at lunch and dinner.
BACK TO JEWELS: Nan Kempner will bring her wit and encyclopedic knowledge of good taste to the podium at East Hampton’s Guild Hall Thursday afternoon to discuss important jewels and the women who have worn them. It will be co-hosted by Christie’s senior vice president Simon Teakle, who heads up the jewelry department at the auction house. Talking points: the dazzlers owned by Elizabeth Taylor, Princess Diana, Audrey Hepburn, Eva Peron and Babe Paley.
