The royal family is paying for the wedding, but the anti-monarchist group Republic is lobbying Parliament to prevent any public money from being spent on security or other wedding-related costs.
Prince Andrew shared the pictures on Twitter ahead of the Eugenie and Jack's marriage at St George's Chapel, Windsor Castle, on Friday.
Eugenie, 28, ninth-in-line to the throne and a director at London's Hauser & Wirth art gallery, and Brooksbank, 32, who works in the drinks and hospitality industry, are copying some of her cousin's plans.
Princess Eugenie and her fiance Jack Brooksbank are preparing to tie the knot in Windsor later. "To have and to hold from this day forward, for better, for worse: For richer, for poorer; in sickness and in health; to love and to cherish, till death us do part, according to God's holy law; and thereto I give thee my troth". But, there's something about her wedding that has Royal fans up in arms.
While Harry's wedding featured a fiery sermon from a U.S. Episcopalian bishop and a gospel choir, Eugenie's will be more traditional with a performance by Italian tenor Andrea Bocelli and the address given by Conner.
The princess and her fiancé invited over 800 people to attend their wedding and guests such as Kate Middleton, Meghan Markle and The Queen are all expected to attend.
In an interview for This Morning, Eugenie admitted pre-wedding nerves were "creeping up".

The Duke and Duchess of Cambridge's children, Prince George and Princess Charlotte, will once again take on pageboy and bridesmaid roles. Dooley said he "didn't watch the royal wedding", though he admitted being in London during the nuptials (the actual wedding took place in Windsor).
Eugenie's sister, Princess Beatrice, is maid of honour.
The couple, who got engaged in January in Nicaragua, have provided attendees with an information packet filled with a list of dos and don'ts for the special day.
It also could just be a color that Princess Eugenie likes, as she's worn various versions of red over the years.
Will Calvert told Sky News this wedding does feel different.
These concerns aren't popular in Windsor's business community, where the surging popularity of the royal family in recent years - and the afterglow of Harry and Meghan's wedding - has helped bring in visitors in recent months.
"We are getting a lot of American and Chinese and Spanish visitors", said Jag Khaira at the Nell Gwynn Tearoom.
