The wedding of Prince Harry and former US actress Meghan Markle is around the corner. But marrying into one of the world’s most exclusive families is not easy. Markle will soon have to learn rituals handed down through the centuries of the British royal family’s existence.

Let's take a look what someone has to know to become a royal bride.

Under the spotlight

Prince Harry and Meghan Markle have been touchy-feely during public engagements - normal for lovers, but unusual for royal family members.

Any public display of affection is extremely rare for the royal family. Queen Elizabeth always walks a few steps ahead of Prince Philip and they are never even seen holding hands. There is no official rule outlawing public affection, but most of the royals keep it to a minimum owing to tradition.

This tradition is why no one has spotted Prince William and Kate Middleton holding hands or kissing ever since their wedding, according to Myka Meier, a royal etiquette expert. However, Prince Harry and Meghan Markle so frequently break this rule with their hand-holding and public affection Meier predicts the rule will eventually fizzle out.

Nevertheless, with the paparazzi in hot pursuit, royal family members should always be seen elegant and modest. As a former "Suits" star, Markle is used to being in front of a camera. But she still must keep in mind at all times that a simple frown, slumped shoulders or a bored look can be picked up by the media in a flash and quickly turn into unflattering attention.
