 A few member churches of the Anglican Communion ordain women as bishops, many more have prepared the legislation for women to become bishops but have not yet ordained a woman to the episcopate (see Ordination of women in the Anglican Communion).Anglican bishops are often identified by the purple clergy shirt and cassock they are entitled to wear.However, bishops are permitted to wear other colours, and a former Archbishop of Canterbury, Rowan Williams, is frequently seen wearing a black cassock.
