Kate Middleton and Meghan Markle use this secret trick to stop their skirts flying up

It has to be said the royal women always look impeccable, whether they're dressing for a formal engagement like Trooping the Colour, or wearing high street to the polo.

In fact, you'd never think they'd suffer from wardrobe malfunctions would you? Because they don't. Even something as common as your skirt blowing up in the wind - I doubt the Queen would approve of a Marilyn moment.

And as with many other strategic wardrobe choices (eg, Diana's bag secret, and the Queen's brooch choices), that's because it was probably carefully planned.

Myka, founder of Beaumont Etiquette, told Marie Claire US that Kate and Meghan wear 'bodysuits and clothes that actually increase static so it’s much hard for something to fly up.'

'I know when I went to finishing school we were taught that when you are on the tarmac, if you do not use weights or heavy weighted material, you make sure it will not fly up by wearing under garments that keep the fabrics connect to your body,' she said.

Very clever.
