A princess is constantly in the public eye, therefore she must look her best at all times. Kate Middleton, for example, goes to the salon for blow outs three times a week. Ugh! Talk about hard work!

Work is for peasants! Being a princess is a full-time job. So once you've officially become a princess, you have to give up any other career path. Kate Middleton has a degree in art history that she's not able to use. But hey, is anyone with a degree in art history really able to use it?

While there's no official law that says a princess cannot vote, the English people heavily frown upon a princess participating in elections. Since the Royal Family is supposed to represent the entire country, taking sides in an election would directly go against that. Sorry, princesses! You can't wear those super cool "I Voted" stickers! 

We all call her Di, but Princess Diana couldn't call herself Di. After becoming a princess, the new royal has to give up her nicknames. The artist formerly known as Kate Middleton now has to go by Catherine — even though "Kiss me, Catherine" doesn't have as much of a ring to it. 

A Princess has to be ready to step up when required. Princess Elizabeth had to become a queen when her father abdicated the throne. If Prince William became King, Kate would become a counselor of state. 

It's not a rule per se. It's more of a guideline. A guideline that gets broken often. Because sometimes a celebrity will pose with a Royal in a very un-royal arm thrown around the shoulder of the Royal as if the Royal is a...gasp!... American celebrity! 

Princesses live in the public eye. Any wrong step will be heavily reported on. Especially a literal wrong step. That would be the trip heard round the world! 

Before 2011, a member of the Royal Family could not marry a Roman Catholic. Now they can, but they have to be a member of the Church of England themselves. It's an old law, but a law that's still on the books to this very day. 

Yes, this is a real rule! In 2008, Prince Andre Duke of York outlawed the playing of Monopoly in the Royal family home “because it gets too vicious.” Sadly, Kate Middleton will never get to be the thimble again. 

It's a rule that when the Queen stops eating, everyone else has to stop eating too. So even if a princess has barely eaten anything, she's done when the Queen is done. Sounds like a great new diet! 

Kate Middleton didn't just marry into the Royal Family. She married into a life of public scrutiny. Because of her position and title, for better or worse, a princess has to expect to be constantly photographed and discussed in the media for the rest of her life. 

This rule is similar to the ban on voting. The Royals represent all of England. Getting involved in partisan politics would definitely not be a non-partisan thing to do! 

This is another very weird, yet very real rule. The British Royals cannot eat shellfish for fear of food poisoning. How much do you want to bet that Kate Middleton's bachelorette party was just going to an all you can eat oyster bar? 

A princess must try to learn as many languages as possible. That way, when she visits with diplomats from other countries, she can speak to them in their language. 

Who knew being a princess meant homework?

Part of a princess's job is showing the country that you care. Which means that a princess must get involved in charity work as much as possible.

Good thing fur is out of fashion! In 1137, Edward III ruled that no one in the Royal Family could wear fur. However, when fur was the height of class, even the Royals couldn't resist breaking decree and donning a fox coat or two. 

There's a specific order to every royal procession that a princess must follow. The reigning monarch leads the way (which is Queen Elizabeth II).  the Duke of Edinburgh (Prince Philip), the Prince of Wales and the Duchess of Cornwall (Prince Charles and Camilla), the Prince of Cambridge and the Duchess of Cambridge (Prince William and Kate). It's basically who's next in line, so it's kind of like a super formal "Follow the Leader."

A Princess will receive many gifts as part of her station. However, no matter awful the gift is, the princess must accept it with a smile on her face. Also, there's no re-gifting allowed!
