Queen Camilla and Princess Kate are banned from wearing these glamorous items before…

Female members of the monarchy must adhere to special rules as all eyes of the world beam on them as they step out in public.

An example of these strict rules includes a ban on donning colourful nail varnish, wearing tights, and cleavages and shoulders must not be shown. Hats are also expected to be worn on royal occasions.

For the men, facial hair has been a no-no as Queen Elizabeth didn’t like it, but Prince William has recently broken this rule with an unshaven look, potentially indicating a relaxation to this protocol.

Boys cannot wear trousers – hence why Prince George is often seen in shorts – and – another peculiar rule affected those wearing jewellery remains in place.

The likes of Queen Camilla and Princess Kate, as well as the royals before them, are not allowed to wear diamonds before 6pm.

Royal etiquette expert Myka Meier told News.com.au, royal women are not allowed to wear diamonds during daytime and can only do so for evening engagements.

“Other jewels are worn pre-6pm,” the royal etiquette expert explained to the news station. “Before 6pm, you’ll see metallics, gemstones, pearls, sapphires.

“At night, you’ll see the diamonds come out, and that’s in order to not come across as flashy in your appearance.”
Princess Kate and Prince William are expected to shape a new kind of royalty, which could maintain or change fashion rules, when the latter takes over, according to another expert.

“[The royal family] realise the power of Kate and the potential of Kate and William as this young, glamorous, dynamic duo who actually do have the ability to reshape and project the monarchy into the future,” royal expert Katie Nicholl explained earlier this year on True Royalty’s Kate: The Making of a Modern Queen.

While it’s unlikely you’ll see royals wearng diamonds in the day, there are other rules members of the family haven’t minded breaking, including Princess Kate.

Both the Princess of Wales and Meghan Markle have gone against one particular rule championed by the Queen – wearing tights with dresses and skirts.
According to royal expert Victoria Arbiter, women must wear tights with their outfits. She said the rule is “the only hard, steadfast rule in terms of the Queen requires”.

However, it has been broken by various different family members including both Kate Middleton and Meghan Markle.
It is also thought that the Queen preferred skirts and dresses to be cut on the knee or just below.
