The most common Anglican design can be similar to the Catholic zucchetto or, far more often, similar to the Jewish yarmulke. A form of the zucchetto is worn by Anglican bishops and is used approximately like that of the Catholic Church. The Anglican "skullcap" differs from the zucchetto primarily in that it is made of six panels, bears a button at centre of the crown, and is of slightly larger dimensions. The other exception is Anglican churches usually (but not always) differ from the Catholic "church violet" for bishops, and instead use purple.
