Supermodels, superstars and fashion designers venerated Jacqueline Kennedy as a stylish and elegant first lady as they celebrated her life during a fund-raising gala at the Metropolitan Museum of Art.

"Jackie O was the best of the best," said Joan Rivers, who attended the exhibit's opening Monday, "Jacqueline Kennedy: The White House Years, Selections from the John F. Kennedy Library and Museum." The exhibit is the first ever retrospective of the White House style of the former first lady. It also features some of her memos, sketches and speeches.

"I think it's a great tribute to her and shows how multifaceted she was," said Maria Shriver, the former president's niece.

Caroline Kennedy asked visitors to consider the substance behind her mother's style. "I know that visitors will enjoy looking at her dresses, but these are just the starting point," she said. "She believed in my father and his vision for America. Together, my parents sought a more just society and a better world, and their example still inspires us today."
