Jacqueline Lee "Jackie" Bouvier Kennedy Onassis (July 28, 1929 – May 19, 1994), was the wife of the 35th President of the United States, John F. Kennedy, and First Lady of the United States during his presidency from 1961 until his assassination in 1963. Five years later she married Greek shipping magnate Aristotle Onassis; they remained married until his death in 1975. For the final two decades of her life, Jacqueline Kennedy Onassis had a career as a book editor. She is remembered for her contributions to the arts and preservation of historic architecture, her style, elegance, and grace.  She was a fashion icon; her famous pink Chanel suit has become a symbol of her husband's assassination and one of the lasting images of the 1960s.  Jacqueline Kennedy became a symbol of fashion for women worldwide. She retained French-born American fashion designer and Kennedy family friend Oleg Cassini in the fall of 1960 to create an original wardrobe for her as First Lady. From 1961 to late 1963, Cassini dressed her in many of her most iconic ensembles, including her Inauguration Day fawn coat and Inaugural gala gown, as well as many outfits for her visits to Europe, India, and Pakistan. In her first year in the White House, Kennedy spent $45,446 more on fashion than the $100,000 annual salary her husband earned as president (He donated the annual salary to charity). Her clean suits with a skirt hem down to middle of the knee, three-quarter sleeves on notch-collar jackets, sleeveless A-line dresses, above-the-elbow gloves, low-heel pumps, and famous pillbox hats were overnight successes around the world and quickly became known as the "Jackie" look.  Although Cassini was her primary designer, she also wore ensembles by French fashion legends such as Chanel, Givenchy, and Dior. More than any other First Lady her style was copied by commercial manufacturers and a large segment of young women. Her influential bouffant hairstyle, described as a "grown-up exaggeration of little girls' hair", was created by Kenneth, whom she had been seeing since 1954, and who continued to style her hair until 1986.

In the years after the White House, her style changed dramatically. Gone were the modest "campaign wife" clothes. Wide-leg pantsuits, large lapel jackets, gypsy skirts, silk Hermès head scarves, and large, round, dark sunglasses became her new look. She often chose to wear brighter colors and patterns and even began wearing jeans in public.  Beltless, white jeans with a black turtleneck, never tucked in, but pulled down over the hips, was another fashion trend that she set.

Throughout her lifetime, Kennedy acquired a large collection of exquisite and priceless jewelry. Her triple-strand pearl necklace designed by American jeweler Kenneth Jay Lane became her signature piece of jewelry during her time as First Lady in the White House. Often referred to as the "berry brooch", the two-fruit cluster brooch of strawberries made of rubies with stems and leaves of diamonds, designed by French jeweler Jean Schlumberger for Tiffany & Co., was personally selected and given to her by her husband several days prior to his inauguration in January 1961.  Kennedy wore Schlumberger's gold and enamel bracelets so frequently in the early and mid-1960s that the press called them "Jackie bracelets"; she also favored his white enamel and gold "banana" earrings. Kennedy wore jewelry designed by Van Cleef & Arpels throughout the 1950s, 1960s and 1970s; her sentimental favorite was the Van Cleef & Arpels wedding ring given to her by President Kennedy.
