Princess Eugenie will be tying the knot on Oct. 12, but she still has to follow some royal protocols.

Grant Harrold, a former royal butler, told Express that Princess Eugenie has to follow protocol starting from her wedding dress down to her wedding reception.

“Princess Eugenie will pick a white or off-white wedding dress as is the royal tradition of all royal brides. She will have myrtle in her bouquet which has been a tradition since the time of Queen Alexandra. The bouquet may be sent to be put on the tomb of the unknown soldier at Westminster Abbey,” he said.

Harrold also said that Princess Eugenie’s wedding ring designer should be the same person that made the bands of the other royals that got married before her.

“The Queen Mother, Queen Elizabeth II, Princess Margaret, Princess Anne, and Diana, Princess of Wales all had their wedding rings made from The Queen’s Welsh gold which was given as a gift from Welsh gold mine Clogau St. David’s in 1911,” he said.

And when it comes to Princess Eugenie’s wedding tiara, she will most likely wear the one owned by the Queen since she has several headpieces.

Royal couples also typically have fruit cake served as their wedding reception, but Prince William and Prince Harry veered away from this tradition. According to Harrold, it is highly likely for Princess Eugenie to serve fruit cake at her nuptials so she could send slices to her family and friends who will be unable to attend.

Princess Eugenie will also have a handful of bridesmaids and page boys in tow on her wedding day at St. George’s Chapel in Windsor Castle. Two of them will most likely be Prince George and Princess Charlotte.

Harrold also said that Princess Eugenie didn’t have to ask the Queen’s permission to wed Jack Brooksbank. After all, the Succession to the Crown Act of 2013 stated that only the first six Royals in line to the throne ought to ask for the Queen’s permission.

However, the former royal butler said that Princess Eugenie might have asked permission from her grandmother out of respect.
