Royal weddings are known for sparing no expense.
Prince Charles and Princess Diana's "wedding of the century" would cost $110 million in today's money. Prince Harry and Meghan Markle served a $71,600 lemon elderflower cake at their reception. And for Prince William and Kate Middleton's big day, security alone cost the couple an estimated $33 million dollars.
Many royal wedding dresses also come with six-figure price tags, taking designers months to create. Even dresses that appear to have relatively modest price tags - such as the Queen's $42,000 dress in 1947 - would be much more expensive today when adjusted for inflation.
Here are nine of the priciest wedding dresses royals have worn, from the least expensive to the most expensive.
