The couple had a traditional and romantic ceremony, but let their hair down at their lavish reception, which was held at Eaton Hall, the Duke's ancestral home. In the afternoon, a private afternoon reception was held, but the evening saw a grander party.
Guests were spotted arriving for the party, and Princess Eugenie had changed from her glorious olive green wedding guest dress into a glitzier thigh-split gown, complete with statement embroidery and a pair of strappy gold heels.
Read on to see the best dressed evening guests from the glittering wedding...
Thomas Van Straubenzee, Lucy Lanigan-O'Keeffe, Charlie Van Straubenzee and Daisy Jenks changed into their wedding reception attire, with Lucy's pastel yellow dress a lovely choice for a June wedding.
No fancy jewellery for Daisy Jenks, who accessorised her floaty dress with bracelets bearing her children's names - perhaps she's a Taylor Swift fan, taking inspiration from there star's friendship bracelet trend?
Metallic shoes seemed to be on-trend for the wedding, with Lucy and Daisy following in Eugenie's footsteps, rocking golden shoes on Lucy's part, and a sparkling orange pair on Daisy's.
