Kate and Meghan appear to be taking after a trend set by the Queen, who's worn the same style of shoe for 50 years.
But why would a Queen with the means to own a footwear collection to rival Imelda Marcos's settle for the same black loafers, for half a century?
While the duchesses have extensive wardrobes, they play it safe when it comes to their footwear, both choosing the same shoes for public occasions.
Kate tends to favour a blush coloured pair of Gianvito Rossie pumps, while Meghan is a fan of black or navy blue Aquazzura heels.
