Kate Middleton and women members of the royal family have very different styles when it comes to fashion.
But whatever they wear, they look pretty much perfect all of the time, with flawless make-up and outfits.
There are lots of rules and traditions Kate has to follow as a member of the royal family.
One of the big no nos for Kate, and all women in the family, is to do with their shoes.
Apparently the Queen doesn't like wedges, so they are not supposed to wear them while in her company.
Speaking to Vanity Fair, a source said: "The Queen isn't a fan of wedge shoes.
"She really doesn't like them and it's well known among the women in the family."
