Suzannah and Stella McCartney had been suggested as possible designers before the big day arrived, but the Queen's granddaughter has instead chosen
to wear a gown by the founders of British label Peter Pilotto for her wedding.
The brand is known for its innovative textile design, paired with a modern feminine silhouette, and Eugenie's dress features a low back as a tribute to surgeons the Royal National Orthopaedic Hospital, who corrected her scoliosis aged 12.
It was a specific request by Eugenie and she worked closely with Mr Pilotto and Mr De Vos on the design.
The trio conducted research into previous dresses worn by members of the Royal Family and the fabric was crafted by the two designers at their studio in east London.
It includes a number of symbols that are meaningful to Eugenie and husband-to-be Jack Brooksbank as motifs.
These include a thistle for Scotland acknowledging the couple's fondness for Balmoral, a shamrock for Ireland as a nod to the bride's Ferguson family, and the York rose and ivy representing the couple's home.
Each has been woven into a jacquard of silk, cotton and viscose blend.
Despite speculation that Eugenie would wear the same York tiara worn by her mother Sarah Ferguson, Duchess of York, during her wedding to former husband Prince Andrew, the Duke of York, in 1986, she has instead opted for the Greville Emerald Kokoshnik tiara.
The tiara, which was lent to her by the Queen, was made by Boucheron for Mrs Greville in 1919 in the fashionable kokoshnik style popularised in the Russian Imperial Court.
It is made of brilliant and rose cut diamonds set in platinum, with six emeralds on either side, and was given to the Queen in 1942.
The tiara is complemented by diamond and emerald drop ear-rings, which are a wedding gift from Mr Brooksbank, while her shoes are satin peep-toe heels by Charlotte Olympia.
And the wedding bouquet has been created by the sister of floral designer Rob Van Helden, Patrice Van Helden Oakes.
It consists of Lily of the Valley, Stephanotis pips, hints of baby blue thistles, white spray roses, sprigs of myrtle from Osbourne House and trailing ivy.
