And this is because it is a well-known fact among the women in the royal family that the 92-year-old is not a fan of the platform-styled heel.
So to act as the perfect granddaughter-in-law, both Meghan Markle and Kate leave their wedges at home on engagements with the Queen.
The Duchess of Cambridge is a known fan of wedges and has made several appearances out wearing her trusted navy and camel shoes.
And in 2016, Kate chose the same style to attend an outing with husband Prince William, pairing a grey pair of Monsoon wedges with a pale pink dress.
But Kate opts to leave her wedges at home when the Queen is around and will instead wear a court high heel.
A source told Vanity Fair: ”The Queen isn’t a fan of wedged shoes.
“She really doesn’t like them and it’s well known among the women in the family.”
Meanwhile, the Royal Family’s newest member 36-year-old Meghan Markle hasn’t been photographed in wedges since her Royal Wedding to Prince Harry in May.
The Duchess of Sussex appears to prefer wearing flat sandals or stilettos.
This is not the only royal dress code Kate and Meghan must abide by when their husband’s grandmother is around.
Wearing dresses without tights is also frowned upon.
Royal fans were quick to notice Meghan’s more formal look when she wore stockings at her very first engagement as a member of the firm.
