When Prince Harry married Meghan Markle in 2018, there was much attention spent in the press comparing Meghan to her new sister-in-law, Princess Kate. But three decades earlier, the dynamics between two different royal sisters-in-law dominated the headlines.

Ferguson married Andrew Mountbatten-Windsor in 1986, and at the time her fun-loving, energetic personality was seen by the public as a breath of fresh air. Diana and Sarah were originally close and shared a similar sense of humor, along with bonding "over their frustration with royal bureaucracy," as biographer Andrew Lownie wrote in Entitled: The Rise and Fall of the House of York.
