A bride veils herself to show humility before God first, and then to her husband. 'Veiling the sacred'..by hiding herself and covering her hair, she is showing the world that she is giving herself to her husband alone. Women veil for some of the most important times in their lives- their First Holy Communion Day, and either their Wedding Day or their Sacred Profession day if they choose the religious life.
Such a modest and pretty lace dress and veil!
