The United Arab Emirates (UAE)
As a tradition in the UAE, the setting of the wedding date marks the beginning of the bride's preparation for her wedding.
Although the groom is also put through a series of preparations, the bride's are more elaborate and time consuming.
She is lavished with all sorts of traditional oils and perfumes from head to toe. Traditionally, she is not seen for forty days by anyone except for family members as she rests at home in preparation for her wedding day.
During the week which precedes the wedding, traditional music, continuous singing and dancing take place, reflecting the joy shared by the bride and the groom's families.
Laylat Al Henna (literally, the night of the henna), which takes place a few days before, is very special night for the bride, since it is a ladies' night only.On this night, the bride's hands and feet are decorated with henna. The back-to-back feasts and celebrations involve both men and women who usually celebrate separately.
