But there is one things that both ladies will never wear around the Queen: wedges. Despite the major comfort factor, Queen Elizabeth just isn't a fan.
"The Queen isn’t a fan of wedged shoes," a source told Vanity Fair. "She really doesn’t like them and it’s well known among the women in the family."
Although the Duchess of Cambridge opts to wear wedges a lot, she has never been photographed wearing them around Queen Elizabeth.
And so it is likely that Meghan will follow the same no-wedges rule around the Queen like Kate, but with her track record of breaking royal fashion protocol, you never know!
