Queen Elizabeth II
Princess Elizabeth was just 21 in 1947 when she tied the knot with a young Royal Navy first lieutenant with royal blood, Philip Mountbatten, who was created Duke of Edinburgh just before they wed.
At one of the most talked-about weddings of the time, the princess wore a long-sleeved satin dress adorned with 10,000 pearls and a four-metre train, as well as the diamond Fringe Tiara by Garrard. During the festivities, she also donned a 1930s Cartier suite that includes a 38-diamond necklace and a tiara with three detachable rose brooches.
