Meghan Markle's marriage to Prince Harry has definitely changed her life in many ways, maybe more than any of us even realize. Now that she is officially the Duchess of Sussex, she has a lot of strict royal rules she must now follow.

Meghan Markle must mind her manners

To be a member of the Royal family, one must follow a rule book of do's and don'ts, according to Eonline reports. These are strict guidelines that must never be taken lightly, especially if she plans on remaining on good terms with the Queen. In fact, there are 17 rules in place to make sure Meghan Markle does just that.

Staying on the Queen's good side is a must

Royal rule number one is that under no circumstances is Meghan permitted to take any selfies with fans. It is considered a sign of disrespect to turn your back on any member of the Royal family, even if it is to try and snap a photo. Royal family members are also never to sign autographs. The Royal signature is used only on royal documents. The new Duchess of Sussex is also banned from using any form of social media.

There are also some major stipulations when it comes to Markle's appearance. Wearing any shade of dark nail polish is a huge no-no. Meghan must also be well prepared when she travels and always travel with an ensemble suitable for a funeral, just in case.

Wardrobe rules also include hemlines on skirts and dresses must be no shorter than one to two inches above the knees, and no little black dresses ever

Hopefully, Meghan Markle has her curtsy in top form as all female members of the family are expected to curtsy when the Queen enters the room and anyone who outranks her royal position.

When entering an event, there is also a major rule on how to enter the room. First to enter is Queen Elizabeth, followed by Prince Philip, Prince Charles, Camila, Prince William, Kate Middleton, Prince Harry and then Meghan Markle.

As for body posture and language, no member of the family should ever cross their legs. It is ankles only and at a slant.

She must also never wear wedge shoes. Dinner time rules state that the nightly meal will be served at 8:30 on the dot and never end past 10:00 p.m. Meghan will also always, with no exceptions, ever be seated next to her husband Prince Harry.

At mealtime, the Queen eats first, and no one is permitted to start until she does, and if she pauses mid-meal, you are expected to stop and wait for her to begin eating again before resuming your own dinner. This rule also applies to sleeping. If you are a guest at the Queen's castle, it is required that you stay up and awake until the Queen falls asleep.

Now here is an odd Royal rule. There is no Monopoly allowed. It was revealed in Reader's Digest by Prince Andrew that Monopoly is not allowed, because it 'gets too vicious.'

There are also two more Royal rules, one that pertains to your form when drinking tea.

No pinkies out! Also, it is highly recommended that the Royal family members refrain from eating shellfish. This is just for safety precautions to avoid getting a nasty case of food poisoning.

This a lot to remember to do on a daily basis. Now we have to wonder if there is any type of becoming a Royal family member prep class you must pass in order to be considered worthy? What do you think about all of these Royal rules Meghan Markle must now follow. Do you think you could handle such rules within your family?
