4. Princess Beatrice, 2020
After postponing their wedding due to coronavirus restrictions, Princess Beatrice tied the knot with businessman Edoardo Mapelli Mozzi in a secret ceremony at Windsor Castle in 2020. The pair exchanged vows in front of about 20 guests to follow the rules regarding large gatherings during the lockdown. For the special occasion, the royal stunned in a hand-me-down wedding dress and tiara loaned to Beatrice from her grandmother, Queen Elizabeth. The vintage ivory Peau de Soie taffeta dress by Norman Hartnell, who was the same designer who crafted Elizabeth's wedding gown, was worn by the Queen at a state dinner during a 1961 visit to Rome. The Queen Mary diamond fringe tiara was also worn by Queen Elizabeth and Princess Anne on their own wedding days.
