COACH’S LOUNGE: Coach toasted its Tony Duquette collection Wednesday night with a cocktail party at its Rodeo Drive boutique hosted by Nina Clemente, Tracee Ellis Ross and Rose Apodaca. While Hutton Wilkinson created a coveted collection retailing for under $700, it was Peggy Moffitt who stole the show in an original Duquette necklace. “He gave this to me so long ago. I love wearing it,” she said as she vamped with her other prized accessory, a vintage Coach bag from the Seventies. “It looks just like the ones in the store today,” she said.
