All of us in Washington, D.C. and indeed all of the world are atwitter with this historic inauguration. I keep wondering whether Barack and Michelle might wear hats to the Inauguration Ceremony-homage to the style and elegance of Jack and Jackie Kennedy and a return to the heady days of Camelot on the Potomac. Jack Kennedy was the last President to wear the traditional top hat to his Inauguration. Here are some lovely photos of their attire at the Inauguration Ceremony and the Inaugural Ball. Mrs. Kennedy's fashion designer was Oleg Cassini. (photos courtesy of Life.com and the John F. Kennedy Library and Museum).
