The 34-year-old royal changed into a different outfit.
Eugenie, the daughter of Prince Andrew and Sarah Ferguson, was one of 400 guests at the wedding.
After the wedding, guests visited the reception at Eaton Hall, the Grosvenor family home.
The newlyweds haven’t said much about the party, but it’s been reported that guests ate lemon cake.
Other guests included Prince William, 41, one of the groom’s ushers, Charlie van Straubenzee and his wife Daisy, whose daughter Clover is believed to have Prince Harry as her godfather, and William Van Cutsem.
As she left the wedding, Eugenie looked glamorous in a black dress with short sleeves and colorful flowers down the front.
She wore high-heeled gold sandals and a gold clutch bag.
Eugenie, who went to Marlborough College like the bride, wore her hair in a chic up-and-down style, letting some of it flow past her shoulders.
The royal at the event without her husband and children finished her look with makeup.
She wore a natural matte base, pink lip, black eyeliner, and dark eyeshadow.
Her party outfit was different from the olive dress she wore at the cathedral.
Eugenie wore a green dress with a cream hat, necklace, and earrings.
Thousands gathered outside the cathedral to see the couple and their guests.
In 2023, the Duke proposed to Olivia at his family home, Eaton Hall, in Cheshire. They had been dating for two years.
