It’s hard to believe it’s been 40 years since a young Diana Spencer tied the knot with Prince Charles at St. Paul’s Cathedral on July 29, 1981. A fairy tale? It was not, as Diana’s marriage to Charles began to unravel not long after ‘I do.’ But the wedding itself was magical, with a horse drawn carriage, poufy dress and princess transformation all included. As a major royals fan, I’ve now rewatched the occasion countless times, but upon each viewing, I always notice something different. And during my latest revisit (which was in honor of the 40th anniversary of the big day), 3 surprising new details really jumped out.
