marital status in clothes

Traditionally Hindu women, once married, would wear sindoor, a red powder, in the parting of their hair. If widowed, they would abandon sindoor and jewelry and wear simple white clothing. Men and women of the Western world may wear wedding rings to indicate their marital status. Also women in the United States, depending on their heritage and/or religion, will usually wear a white gown, although some movie stars have been known to wear a black party dress for their wedding. Observant Jewish women cover their hair if they are married. There is a sect of Judaism in which girls who are old enough to be looking for a husband wear their hair in two braids as opposed to the one braid they wore before they were of a marriagable age.
