Royal etiquette expert Myka Meier revealed that Kate, 40, uses strapless and seamless underwear under her outfits. 

Myka, who is the founder of Beaumont Etiquette and trained under a member of The Queen’s Royal Household, wrote on Instagram: “Royal Style Hack Alert. 

“Ever wonder why you never see bra straps?! 

“Swipe to see a secret trick which is a must-have royal wardrobe piece!”

Myka then showed a photo of a nude-coloured strapless shapewear piece which she claims is key for looking polished in public.

Speaking to Fabulous, Myka said: “Underwear and bras are also considered private intimate wear, and for royals to put intimate apparel on display would simply not be done. 

“There are a few options to hide bra straps, with one option being a bra that is actually sewn into the piece.

“A second option is strapless shapewear, which is a one-piece that either snaps at the bottom or has legs attached. 

“You can buy them in almost any skin tone so they appear transparent and don’t show through clothing. 

“You want the attention to be on the beautifully tailored and designed garment and not the undergarments. 

“Undergarments showing can take away from an amazing outfit.”

The etiquette pro also stressed the importance for royals such as Kate and Meghan Markle to avoid a dreaded VPL (visible pant line) in trousers or a form-fitting dress.

She advised that seamless knickers, undergarments or shapewear will be used.

Myka, who has released a best-selling book Modern Etiquette Made Easy, said that John Lewis has a line of shapewear and is a brand known to be a royal go-to. 

Previously, the etiquette expert said Kate and Meghan Markle have a sneaky trick to stop their skirts blowing up in public and revealing their underwear.

She said: “Often they wear body suits and clothes that actually increase static so it’s much harder for something to fly up.

“So you have an undergarment that is almost like a bodysuit, that is one tactic that is used.

“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 undergarments that keep the fabrics connected to your body.”

The Queen was said to use weights along the hem of her dresses, and these were reportedly sourced from the curtain accessories section of the department store, Peter Jones.
