An etiquette expert believes Kate Middleton almost always carries a clutch bag to avoid awkward hand shake situations.
Meanwhile, Her Majesty the Queen nearly always carries a handbag with a short strap — and she often holds it with both hands, too.
Future royal Meghan Markle, however, seems less fazed by contact with the public.
Senior members of the royal family, like the Duchess of Cambridge, almost always carry a clutch-style handbag — and there's a good theory for why that is:
Why the royals wear clutches
Why the royals wear clutches
Myka Meier, the founder of Beaumont Etiquette, told Good Housekeeping: "When the Duchess is at an event, she holds her bag in front of her in both hands when shaking hands might be awkward."
"Or she can place it in one hand to have the other free. It never gets tucked under an arm or placed on the ground or table."
If you look back through the photo archive, you'll rarely spot Kate Middleton without a clutch in hand. She's most often photographed holding it with both hands in front of her during public appearances.
Meanwhile, the Queen is a fan of handbags with a short strap, which she can either carry with both hands or hang off her wrist or arm.
Meghan Markle opted for a similar formal style when she attended the Christmas Day church service with the royal family in King's Lynn...
...But last week, during a visit to Edinburgh Castle, she opted for something a little more relaxed, by way of a simple crossbody bag, prompting some observers to suggest she had once again defied royal tradition.
Markle doesn't appear to be fazed by contact with the public, and it was only last week that she made headlines for hugging a charity worker at a separate appearance.
While at Edinburgh Castle, she used her free hands to accept gifts from and interact with well-wishers.
If a royal must use the restroom during a meal, they don’t announce it to the table. Instead, they apparently simply say “Excuse me,” and that’s that. (If only your toddler would do the same.)
YOU MUST ADDRESS ROYALS PROPERLY
This one’s a little confusing. Apparently, when you first meet the queen, you should address her as “Your Majesty” and then “Ma'am.” For other female members of the royal family, you should use “Your Royal Highness,” and then again “Ma'am” in later conversation. For male royals, it's “Your Royal Highness” and then “Sir.” And under no circumstances should you address the queen as “Liz.”
THERE ARE NO AUTOGRAPHS OR SELFIES ALLOWED
So put that selfie stick away.
TIARAS ARE ONLY WORN BY MARRIED WOMEN
No ring? No tiara.
THEY RARELY EAT SHELLFISH
This isn’t a requirement, but a wise rule that many royals, including Queen Elizabeth, adhere to because of the increased likelihood of food poisoning.
While the official website for the British Monarchy says that there are “no obligatory codes of behaviour when meeting the queen or a member of the Royal Family,” it also states that many people wish to observe the traditional forms. That means a neck bow (from the head only) for men and a small curtsy for women.
WHEN THE QUEEN FINISHES EATING, THEN SO MUST YOU
Dining with royalty? No extra portions for you.
THE QUEEN SIGNALS WHEN A CONVERSATION IS OVER
If you see Her Majesty move her purse from her left arm to her right, then it’s time to stop talking. That apparently signals to her staff that she’s ready to move on.
SIX RAVENS MUST LIVE AT THE TOWER OF LONDON
According to legend, at least six ravens must remain at the giant fortress or else the monarchy will fall. But no one actually believes that, do they? Well, apparently so, since there are indeed seven (one spare) birds living at the Tower currently.
ROYAL WEDDING BOUQUETS CONTAIN MYRTLE
This tradition started with Queen Victoria and continued with the Duchess of Cambridge's marriage in 2011. This pretty flower symbolizes good luck in love and marriage. Aww...
