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.
White wedding The term originates from the white colour of the wedding dress, which first became popular with Victorian era elites after Queen Victoria wore a white lace dress at her wedding. However, the term now also encapsulates the entire Western wedding routine, especially in the Christian religious tradition, which generally includes a ceremony during which the marriage begins, followed by a reception.
