Eugenie and Jack’s wedding will be held at St George’s Chapel on October 12, the same venue where cousins Meghan and Harry married earlier in May.
The princess has given few details about the ceremony, and has vowed to keep her wedding dress design a secret until her big day.
However, Eugenie might have let slip a massive clue in her most recent Instagram post.
Eugenie posted a picture of herself from her 2016 Harper’s Bazaar shoot on her Instagram page, dressed in a bespoke Alberta Ferretti lace gown.
Eugenie stunned in the gorgeous pink and floral lace gown by the Italian designer, posing for a series of exclusive pictures for the magazine.
The Instagram post may have given us a vital clue to Eugenie wedding dress, as her royal wedding date draws closer.
Eugenie confirmed her wedding dress will be designed by a UK-based designer, so it is unlikely we will see an Alberta Ferretti gown.
She previously told British Vogue: “[The dress] is the one thing that I was really decisive about. As soon as we announced the wedding, I knew the designer, and the look, straight away.”
The princess, who is a campaigner for environmental issues, vowed to make her wedding completely plastic free.
She told Vogue: “My whole house is anti-plastic now – and Jack and I want our wedding to be like that as well.”
Eugenie and Jack were in a relationship for seven years before announcing their engagement in February.
Their ceremony is expected to cost £2 million, less than Meghan and Harry’s wedding which amounted to £45 million – with £31 million for security.
Eugenie and Jack’s wedding is set to be a big one, as the couple have invited nearly 850 guests – 250 more people than Meghan’s wedding in May.
Eugenie and Jack will be inviting a star-studded guest list to their wedding – thought to include George and Amal Clooney, David and Victoria Beckham, Robbie and Ayda Williams.
About 400 wedding guests will also be invited to a black-tie reception at the Royal Lodge in Windsor Great Park later in the evening, including members of the Royal Family.
They have also invited 1,200 members of the public, who will get a chance to witness the ceremony, and also catch a glimpse of members of the Royal Family from inside the Windsor Castle grounds.
Announcing details of the wedding, a spokesman for Buckingham Palace said: “The couple are delighted to announce an opportunity for 1,200 people from across the United Kingdom to be invited into the grounds of Windsor Castle to share the experience of their special day.
“The attendees will view the arrival of the congregation and members of the Royal Family, listen to a live broadcast of the marriage service and watch as the bride and groom depart St George’s Chapel at the end of the ceremony.”
