French-born American fashion designer Oleg Cassini helped create the classic “Jackie look”, designing many of her vibrant pillbox hats, candy-coloured coats and those sleeveless A-line shifts she loved – at formal functions she often accessorised them with white gloves. But she also shopped at Chanel, Givenchy and patronised US designer Norman Norell. Her approach extended beyond what she wore to how she lived - her overhaul of the White House interiors got tongues wagging.
While her husband’s time in office was cut tragically short (JFK was assassinated in Dallas in 1963) Jackie never left the spotlight. Her second marriage to Greek shipping magnate Aristotle Onassis saw her snapped in chic spots around the world (her holiday style is legendary). After his death in 1975, she began working as a book editor in New York. That came with a whole new wardrobe including those signature trench coats, oversized shades and Gucci scarves. Her '70s maxi dresses from this period look pretty inspiring to us in the current fashion moment, and no-one knew her way around tailoring quite like Jackie.
