But the celebration didn't stop there. After the ceremony, the newlyweds hosted a dinner party, before which Princess Eugenie changed into a stunning Zac Posen gown.
The next day, the bride and groom continued the festivities, hosting a second wedding celebration, complete with a ferris wheel, an inflatable slide and a performance by Ellie Goulding.
Despite there being a social media ban on the event, as usual, some guests broke the rules, posting photos and videos showing the incredible day.
One thing's for sure: Princess Eugenie and Jack know how to throw a party.
