Not many royal fans will know that Kate, , broke a 350-year-old tradition on her wedding day, simply because she chose to wear her hair down for her nuptials. According to the documentary, 'William & Kate: The Journey', Kate was encouraged by royal officials to wear her hair up, something she stood firmly against.

Speaking in the documentary, royal expert Ashley Pearson said: "Royal sources tell me that the royals indicated very strongly to Kate that they would prefer her to wear her hair up for this very special occasion." It is custom for royal brides throughout history to wear their hair up on their wedding day, and the expert explained further: "Kate had her heart set on wearing her hair down with long flowing curls, which is her favourite way to wear it and actually William's favourite as well.

"They ended up compromising on her look." The royal hairstylist responsible for creating the look was stylist James Pryce - Richard Ward Salon.

Kate's hairstyle wasn't the only tradition broken in the run-up to their wedding. Prince William broke a standard tradition of his own, foregoing asking the bride's father for her hand in marriage, as he revealed in their 2010 engagement interview.

"So I thought, if I ask Kate first, then he can't really say no. So I did it that way around. I managed to speak to Mike soon after it happened, really, and then it sort of happened from there," referring to Kate's father, Michael Middleton.

Together, William and Kate also uprooted the tradition of having a limited guest list of their own friends. Speaking on BBC's documentary 'Royal Wedding: A Day to Remember', royal expert Roya Nikkhah says that the prince was confused when he was handed the suggested guest list and realised he and Kate didn't really know anyone on the list. She explained: "When the guest list was drawn up [William] was very bemused and had a conversation with the Queen to say 'I don't know any of these people'.

"He wasn't very happy about it. The Queen [Queen Elizabeth II] just said to him, rip that list up and start where you want to start from and invite who you want - and that's what they did."

The couple ended up filling Westminster Abbey with their friends, family, old colleagues, school pals and people who had supported them over the years.
