There’s no question Jacqueline Bouvier Kennedy Onassis was an icon in every sense of the word. Forever beloved, her fashionable visage still endures in our memories to this day, on what would have been her 85th birthday (pictured above in 1962 during a trip to India and Pakistan). When Jackie became First Lady, the public was instantly enthralled by her chic and simple approach to clothing and beauty. From the the white Oleg Cassini gown and cape she chose for her husband John F. Kennedy’s inaugural gala to her collection of boxy Chanel suits and perky Halston pillbox hats, she was a figure who set trends and lived by her own rules.

As a woman who epitomized glamour, Jackie’s name came to stand for a complete lifestyle. From her trademark style to her impeccable manners, she was a woman the public adored and followed, prompting many to ask, “What would Jackie Kennedy do?” She shaped fashion history by guiding women away from the tight waists, crinolines, and over-styled hairdos of the 1950s and into sleek shifts and a more natural approach to makeup that played up the eyes.

Americans weren’t the only ones enchanted and taken by the First Lady—she charmed audiences worldwide. The extraordinarily welcoming reception she received on a visit to Paris in May 1961 prompted President Kennedy to remark, “I do not think it altogether inappropriate to introduce myself… I am the man who accompanied Jacqueline Kennedy to Paris, and I have enjoyed it.”
