Step-by-step explanation:
The single layer veil that covers the bride's face during the processional is called a bridal veil or sometimes simply a veil. This tradition has ancient roots, with brides historically being adorned with six braids, a style also used by the Vestal Virgins to signify chastity. In many wedding traditions today, the veil remains a symbol of purity and is part of the ceremonial attire that can represent various aspects of a bride's identity and cultural heritage.
