Her fiance, the Duke of Orleans (later the King of France), was rather tall. The duke was also known to have a beautiful mistress. In order to compete with the King’s elegant French mistress, Catherine had two-inch heels made to give her a more captivating physique. These high heels later became a fashion staple associated with wealth and privilege.
