Royal women usually hold bags in their left hand: Handbags are a common accessory during royal outings where a lot of meeting and greeting takes place. You can spot Meghan Markle and Kate Middleton holding purses in their left hands simply so their right hand is free to wave, shake hands, and greet the public.

Queen Elizabeth prefers dresses and skirts over pants: Meghan is quite fond of pantsuits—but apparently the Queen prefers skirts and dresses to trousers. Princess Diana was known for wearing tuxedo suits to events, so while Her Majesty doesn’t prefer the style, it may not be completely prohibited.

Wedding dresses need the Queen’s approval. It’s a tradition that the Queen needs to approve the final version of a royal wedding dress. Apparently, Queen Elizabeth had to approve of Kate Middleton’s Alexander McQueen gown in 2011, and she did the same with Meghan Markle.

Colorful nail polish isn’t allowed: Every time you see Queen Elizabeth or Kate Middleton step out, you might notice their nail color is always neutral. They either wear subtle pinks or clear polish when on official business because only natural looking nails are allowed at royal events.To illustrate this point, please see the Duchess’ natural nails while she’s taking a swig of beer.

Tiaras are worn only to the fanciest of royal events, and typically, they’re worn for the first time by brides. Kate Middleton borrowed Queen Elizabeth’s Cartier for her wedding to Prince William in 2011, and she’s even worn Princess Diana’s tiara on several occasions.

The Queen wears bright clothing — but not because she loves color.

You’d be hard-pressed to find a photo of Queen Elizabeth NOT wearing bold colors—and for good reason. This is because “She needs to stand out for people to be able to say ‘I saw the Queen.’” If she’s wearing one of her brightly-hued monochromatic outfits, the public can easily catch a glimpse of her in a large crowd.

The Queen wears hats due to an old tradition.For basically every formal occasion, the Queen wears a hat that perfectly matches her bright outfits. Apparently it comes from a very old tradition that women should keep their hair covered. Up until the 1950s, ladies were very seldom seen without a hat as it was not considered ‘the thing’ for ladies to show their hair in public, Diana Mather from The English Manner etiquette consultancy told BBC.
