But Prince Andrew thinks his daughter's wedding day will be better because Eugenie and Jack. have more friends.
"This is meant to be a family wedding", Prince Andrew said earlier.
Fourth in line for the throne, the shortest bridesmaid bounded up the big steps.
After the ceremony at St. George's Chapel, the newlyweds were photographed leaving Windsor Castle for an evening reception at the Royal Lodge, the Duke of York's official residence since 2003, and the Queen Mother's former home.
Eugenie's elder sister Princess Beatrice, the maid of honour, read a passage from the The Great Gatsby describing the smile of the title character, a rich man famed for throwing parties for the 1920s NY glitterati.
The Queen watched the ceremony in the historic castle, along with the Duke of Edinburgh, the Prince of Wales, Harry and Meghan, and the Duke and Duchess of Cambridge.
The couple got engaged in January when Brooksbank, 32, proposed during a holiday trip to Nicaragua.
Eugenie works at a contemporary art gallery.
Queen Elizabeth II and her husband Prince Philip attended the wedding, along with Prince Charles, Prince William, Prince Harry and other senior royals. There was no sign of 5-month-old Prince Louis, William and Kate's youngest child.
"It's nerve-wracking and a bit scary and all the things that come with getting married, but at the end of the day you get to marry the person you love", she said.
The ceremony was overseen by the Dean of Windsor David Conner and charity guests and 1,200 members of the public were invited into the grounds for the occasion.
