”Jacqueline Kennedy: The White House Years” at NYC’s Metropolitan Museum of Art (through July 29) ON DISPLAY Nine galleries showcase more than 80 original outfits, including Jackie’s 1961 Oleg Cassini inaugural-gala gown; the White House restoration she spearheaded; and her fashion-savvy notes and sketches. Guest curator/Vogue editor Hamish Bowles gathered almost all the artifacts from the John F. Kennedy Library and Museum in Boston. STYLE AND SUBSTANCE ”She never wanted the clothes to be the center of attention,” says the Met Costume Institute’s Bernice Kwok-Gabel of the former First Lady. ”They never dominated her or what she stood for.” FULL HOUSE With a $3,500-per-head dinner, and cohosted by L’Oreal, Vogue‘s Anna Wintour and designers Oscar de la Renta and Carolina Herrera, the April 23 gala opening attracted the likes of Laura Bush, Diana Ross, and Renee Zellweger. JACKIE O-BSESSION Bergdorf Goodman, which hosted last month’s party for both Pamela Clarke Keogh’s book Jackie Style (HarperCollins, $45) and Prescriptives’ Camelot Collection, now offers Morgenthal-Frederics’ ”classic O” sunglass set ($280), and featured store windows reflecting the furniture and fashions of the Kennedy White House era.
