NEIGHBORLY CONDUCT: Diamond jeweler Graff and luxury brand J.Mendel doubled up for a good cause. On Wednesday night, the two brands, which are neighbors on Madison Avenue, hosted a night of shopping benefiting Lenox Hill Neighborhood House Kids in Playland. The likes of Jennifer Creel, Lisa Airan and Coralie Charriol — all dressed in J.Mendel — perused the jewels, furs and dresses at either store. While the guests of the joint party were identical, the vibes were decidedly different in the two stores. "It's very chic in here, everyone is drinking Champagne," mused designer Gilles Mendel to Henri Barguirdjian, president and chief executive officer of Graff America. "At my store there's vodka."
MOTHER'S DAY SPECIAL: Few mother-and-son relationships are as iconic in fashion as the one between Michael Kors and his mom, Joan. On Thursday, the point was driven home, or at least to Bergdorf Goodman, when the two hosted a private luncheon for 36 American Express Centurion and Platinum members in honor of Mother's Day. During the lunch at the store's BG eatery, Amex cardholders got to see 22 looks from Kors' fall collection, with the designer offering quips and anecdotes about himself and the specialty store. "I wanted to do a trunk show, but I didn't even know what that meant," he recalled. "But I knew Bill Blass did them." He clearly knows all about them now. Post-lunch, he joined the cardholders in the third-floor Kors boutique, where he helped them make their fall orders.
