These poses are thought to be very purposeful: each of the positions that the Queen, Meghan and Kate tend to arrange their bodies in while seated are elegant and protect their modesty from low camera angles.
That’s according to royal etiquette expert Myka Meier, who talks Yahoo UK through the four positions that the key females in the Royal Family regularly use in video series ‘The Royal Story’.
You’ll likely recognise the Queen’s pose. The 93-year-old monarch has adopted the same seated position for decades.
She locks her knees and ankles together - “as if tied with a rubber band,” says Meier - and puts one hand over the other or clasps her typically-gloved hands in her lap. Her shoulders are pulled back and her back straight.

You might also be familiar with Meghan’s signature pose: the ‘Sussex Slant’ as it’s been dubbed.
The 38-year-old tends to cross one knee over the other, while seated, with her ankles locked together.
She’s a lot looser with her hands and arms than the Queen and is often clasping a clutch bag.
‘The Cambridge Cross’ is Kate’s go-to position, says Meier. The mum-of-three locks her knees and ankles together and crosses one ankle over the other.
Both Meghan and Kate also work ‘The Duchess Slant’, says Meier.
Sat on the edge of their seat, with their legs at an angle and forming a zig-zag shape, this stance ensures no unwanted images are taken from cameras positioned at low angles.
