According to royal commentator Catherine Ostler, Camilla was “desperate” to persuade Kate to wear a tiara for her wedding.
The Duchess of Cambridge had deliberated wearing flowers in her hair, but the Duchess of Cornwall allegedly had her friends intervene on her behalf.
Ms Ostler wrote in the Mail Online in 2011: “While Charles and Camilla have no wish to be seen as extravagant or out of touch, they believe there is a level of formality and grandeur beneath which a royal wedding must not sink.
“In their sixties, their tendencies are traditional and patrician.
“However, William and Kate are decades younger and have been guests at a plethora of weddings in their peer group, so are keen by natural instinct and public relations savvy not to be old-fashioned or stuffy.
“They want to have a royal wedding, be like their friends and be ‘of the people’ – something that Camilla would regard as trying to have their royal wedding cake and eating it.”
The tiara debate was one of many alleged disagreements between the older and younger generations of royals in the build up to the wedding.
The Cambridges broke tradition by choosing Westminster Abbey as the wedding venue rather than St Paul’s Cathedral while Prince Harry, at his own insistence, wanted to be called ‘best man’ rather than the traditional royal term ‘supporter’.
Ms Ostler added: “The Buckingham Palace lunch – unbelievably, according to the old guard – is a very middle-class buffet.
“Charles is hosting the evening dinner for 300, which is expected to be a more lavish sit-down affair.
“Then there is the guest list – several of Prince Charles’s Sloanier country shooting friends are said to be put out that they have been sidelined in favour of worthier sorts who toil away for charities connected with the Prince’s Trust and William and Harry’s good causes.
“This week, it also emerged that William and Kate have decided that in this more egalitarian age, guests should be shuffled round town on the day in mini-buses.
“Again, note that Charles and Camilla have chosen not to join them, preferring to take his chauffeur-driven Rolls-Royce instead.”
A royal aide at the time noted that there was “no way” that Charles would arrive at Westminster Abbey in a bus.
As expected the Prince of Wales arrived by car instead.
Ms Ostlere said: “You might say William and Kate want to keep it real, while Charles and Camilla want to keep it royal.
“At heart, Charles and Camilla have upper-class leanings and William and Kate, to a certain extent, share middle-class tastes.”
Of course, on the day itself, Kate wore the Cartier Halo tiara which was lent to her by the Queen.
It had initially been commissioned by George VI in 1936 as a gift for the Queen Mother.
The tiara is made up of 739-brilliant cut diamonds and 149 baguette diamonds.
Royal tradition dictates that one must only be worn by brides on their wedding day or by married women, as in ancient antiquity the tiara is an emblem of the loss of innocence.
