The bride's veil and bouquet are of greater antiquity than her white gown. Her veil, which was yellow in ancient Greece and red in ancient Rome, usually shrouded her from head to foot, and has since the earliest of times, denoted the subordination of a woman to man. The thicker the veil, the more traditional the implication of wearing it.  According to tradition, it is considered bad luck for the bride to be seen by the groom before the ceremony. As a matter of fact, in the old days of marriage by purchase, the couple rarely saw each other at all, with courtship being of more recent historical emergence.
