Eugenie's stunning gown, which featured a fitted bodice and full pleated skirt, was designed by Peter Pilotto and Christopher De Vos, who founded the British-based label Peter Pilotto, in London in 2007. The dress has a neckline that folds around the shoulders to a low back that drapes into a flowing full-length train. The low back feature on the dress was at the request of Eugenie, who had surgery at 12 years old to correct her scoliosis and opted to show off her scar by forgoing a veil on her wedding day.
The fabric of the dress includes a number of symbols that are meaningful to Princess Eugenie, including a thistle for Scotland as a reminder of the couple's love for Balmoral, a shamrock representing Sarah Ferguson's Irish heritage, the White Rose of York and an Ivy representing the couple's home of Ivy Cottage.
Meanwhile, Jack wore a black and grey morning suit with a vivid blue waistcoat, made by tailors at Huntsman on Savile Row. (No word on if his glasses, which the groom sweetly wore to see Eugenie walk down the aisle, will be part of the display!)
Also part of the exhibition – for the first time on public display! – will be the Greville Emerald Kokoshnik Tiara, which was lent to her by the Queen. The tiara is made of brilliant and rose cut diamonds pavé set in platinum, with six emeralds on either side. She also wore diamond and emerald drop earrings which are a wedding gift from Jack.
Her bridal shoes are satin peep-toe heels by Charlotte Olympia.

The move follows in the footsteps of Meghan Markle and Prince Harry, whose wedding ensembles also went on display at Windsor Castle following their May nuptials.
Visitors to "A Royal Wedding: The Duke and Duchess of Sussex" exhibit, which ran from Oct. 26 to Jan. 6, were able to hear the couple themselves talk through every stage of their wedding planning via the exhibition's audio guide (a royal first!).
In addition to seeing Meghan's bespoke wedding dress and veil created by British designer Clare Waight Keller, artist director at Givenchy.
"I wanted a female designer, that was very important, I wanted a British designer because I wanted to embrace my new home in that way," Meghan said in the audio recording as she chats to the exhibition curator Caroline de Guitaut, adding: "I wanted something that felt reflective of the world in a way."
Visitors also saw the sparkling diamond and platinum bandeau tiara lent to Meghan by Harry's grandmother Queen Elizabeth for the royal wedding held on May 19th.
Royal fans still have a chance to see Meghan and Harry's wedding outfits in person. They will be displayed again at the Palace of Holyroodhouse, the Queen's residence in Edinburgh, Scotland, beginning June 14, 2019.
