Prince Charles and the Duchess of Cornwall with Pope Benedict XVI
Prince Charles and Princess Diana with Pope John Paul II
The Duchess of Cornwall is not, as one tabloid suggested, emulating the late Diana, Princess of Wales. It is protocol for women to wear black and to cover their heads when meeting the Pope. The only exception being the privilège du blanc. A privilege afforded to female Catholic Monarchs, and to female Catholic Consorts of Monarchs, wherein they are allowed to wear white when in an audience with the Pope.
