who gets to wear white lace at the vatican
Privilège du blanc A reigning Catholic queen or princess retains this privilege at the discretion of the Pope, by remaining a Catholic in good public standing, through marriage to another Catholic monarch, or simply granted by the Pope at his dispensation.[citation needed] Catholic royalty may freely choose whether to exercise the privilege depending on the importance of occasion; if they refuse, this is termed as "declining the privilege"[citation needed], and the choice to wear black garments at certain points of Papal audiences does not negate her privilege to be dressed in white.
