For instance, while a black lace veil was considered traditional for most during a visit to the Vatican, Catholic queens wore white lace. There are only seven women in the world currently given the privilege of the white while meeting the Pope: the seven current Catholic queens and princesses. Those royals are Spain's Queen Sofía and Queen Letizia, Belgium’s Queen Paola and Queen Mathilde, Grand Duchess Stéphanie and María Teresa of Luxembourg, and Princess Charlene of Monaco.
