Ever since Kate Middleton joined the royal family, she hasn't ruffled too many feathers.
She's sophisticated, absolutely gorgeous, and a great future Queen. Unfortunately for Meghan Markle, she's viewed as the more likable royal bride of the two.
But Kate isn't entirely a royal goody-good. She's broken some rules here and there, too.
Here are 10+ of them.
In case you don't know what that is, it's when royal females sit with their legs slanted to one side with their ankles together.
This just looks more proper compared to sitting with their legs open.
Physical contact with royals in photos is a major no-no. And yet, Kate didn't shrug off LeBron's arm in this photo.
She and Prince William's awkward face here pretty much says it all.
If I had the 12-carat sapphire that was worn by the late Princess Diana, I know that I would never want to take it off.
But to each their own, as Kate has been spotted without it several times.
Like when she was photographed without it in January when visiting a children's hospital.
Later, her office told Hello! that she did it to avoid any hygiene risks.
In case you didn't know, the Queen's choice of nail polish is Ballet Slippers by Essie. It's a nude, pinkish color that is very sophisticated.
So whenever Kate goes for a bright mani, she's going against the grain.
By now, you're probably well-aware of the fact that the Queen loves her bright colors.
They look great on her and it helps her stand out in large crowds.
The year before, she showed up dressed in a color-appropriate color: an all-black ensemble.
So why the switch?
It's an unwritten rule that royal females don't wear skirts or dresses that are more than three or four inches above her knee.
Yet, Kate has broken this rue on more than one occasion.
While Meghan Markle was the first royal to wear blue denim to an official royal event, Kate has been a fan of denim for years.
This goes against strict rules of proper attire for royal engagements.
The Queen has a bone to pick with the heel. "The Queen isn't a fan of wedged shoes," a royal source told Vanity Fair.
"She really doesn't like them and it's well known among the women in the family." This certainly makes Kate's favorite Stuart Weitzman pair quite awkward.
Female royals must wear nude stockings while working (i.e attending events), according to royal etiquette expert Myka Meier.
If that were it, Kate would have been fine with her black tights. But Meier said that they have to be in the color nude.
Royal etiquette expert Myka Meier spoke to The Sun about why this rule is so important.
"When your chin points down or up it gives the impression that you’re not paying attention or not interested in what’s happening."
It sounds weird, but most royal females have weights hemmed into their dresses to avoid pulling a Marilyn Monroe from the wind.
It's a good style tip, but one that Kate has skipped throughout the years.
It's not just her wedges that are a problem.
Kate often skips the three-inch heel rule by opting for something taller. Like when she wore four-inch Jimmy Choo “Romy” ombré glitter pumps to a musical event in February.
There are a lot of royal Christmas traditions that you might not know about. For instance, did you know that the royals don't open Christmas presents on Christmas Day?
They do it on Christmas eve instead.
Kate and William broke this rule twice now by spending Christmas with Kate's family during her first pregnancy and then when Charlotte was a baby.
These earrings were the subject of controversy when Kate wore them to the baptism of Prince Harry and Meghan Markle's son.
That's because people saw them as Kate trying to "upstage" the couple on their special day.
"It would have been a nice gesture of hr to lend them to Meghan instead," another wrote.
Since there was already alleged drama between Prince William and Kate and Prince Harry and Meghan Markle, the earring drama certainly didn't help.
