There's nothing quite like a good wedding to bring people together, but when it's a royal wedding in the cards, things get even more interesting! At Princess Eugenie's big day on Oct. 12, key figures surrounding the royal family will be stepping into the spotlight — from the practically royal Pippa Middleton with big sister Kate to the almost-princesses Chelsy Davy and Cressida Bonas and former royal bride Sarah Ferguson. This is what you can expect from Eugenie's nuptials, the second biggest British royal wedding of 2018.
