JACKIE KENNEDY EXCLUSIVE: Rare Pics

Jackie in close-up, October 1960. "Her bouffant hairdo is becoming a by-word in beauty salons," wrote LIFE in January 1961, and "despite herself, [Jackie] is becoming the nation's No. 1 fashion influence." Fifty years later, her style is still referenced: Just take a look at Michelle Obama’s similarly pumped-up hair and pearls. (See First Lady style through the years.)
