Not since Jackie Kennedy, who created fashion crazes with her pillbox hat, oversized sunglasses, and leopard print coat, have we had a first lady admired for her sense of style as much as her political responsibilities. Not, that is, until Michelle Obama stepped into the White House four years ago.   Having already asserted herself as a major trendsetter through her expert mixing of high-end and affordable pieces, our returning First Lady takes sartorial risks unapologetically. Will she continue to follow in the footsteps of her most fashionable predecessors?   Only time will tell, but the daring yet practical Mrs. Obama seems to be up for the challenge. As we embark on another four years, below enjoy photos through the ages of a few of our top First Lady fashion icons.       Frances Cleveland First Lady, 1886 – 1897                           Edith Roosevelt First Lady, 1901 – 1909                         Grace Coolidge First Lady, 1923 – 1929                         Mamie Eisenhower First Lady, 1953 – 1961                           Jacqueline Kennedy First Lady, 1961 – 1963                       Claudia “Lady Bird” Johnson First Lady, 1963 – 1969                         Pat Nixon First Lady, 1969 – 1974                           Betty Ford First Lady, 1974 – 1977                           Nancy Reagan First Lady, 1981 – 1989                         Michelle Obama Current First Lady                         (Lead image, credit BlackEnterprise.com)
