The Most Expensive Wedding | Prince Charles and Lady Diana Spencer | $110 Million

Prince Charles and Princess Diana’s 1981 wedding was considered a fairy-tale wedding that a lot of women dreamed of. Aside from being derived straight from a fantasy book, it was also the most expensive wedding ever. Accounting for inflation, if the marriage happened today, it cost a whopping $110 million, which is way better expensive than the chairman of Queens Park Rangers football club’s wedding.

Although it has been almost four decades since the wedding happened, no celebrity wedding has matched or even came close to the degree of the lavishness of this grand event. There are about 3,500 people attended the event, along with 750 million viewers on TV. Aside from the wedding itself, as royals, they also had to pay for security, not to mention the 25-foot train gown with 10,000 pearls and the 225-pound, five-foot-tall cake.
