fasten the garment. A French cassock also has buttons sewn to the sleeves after the manner of a suit, and a slightly broader skirt. An Ambrosian cassock has a series of only five buttons under the neck, with a sash on the waist. A Jesuit cassock, in lieu of buttons, has a fly fastened with hooks at the collar and is bound at the waist with a cincture knotted on the right side. The ordinary Roman cassock worn by Roman Catholic clerics (as distinct from that worn as choir dress) is black except in tropical countries, where because of the heat it is white and usually without shoulder cape (pellegrina). Coloured piping and buttons are added in accordance with rank: black for priests, purple for chaplains of His Holiness; amaranth red for bishops, protonotaries apostolic and Honorary Prelates; and scarlet red for cardinals. The 1969 Instruction on the dress of prelates stated that for all of them, even cardinals, the dress for ordinary use may be a simple black cassock without coloured trim. A band cincture or sash, known also as a fascia, may be worn with the cassock. The Instruction on the dress of prelates specifies that the two ends that hang down by the side have silk fringes, abolishing the sash with tassels. A black faille fascia is worn by priests, deacons, and major seminarians, while a purple faille fascia is used by bishops, protonotaries apostolic, honorary prelates, and chaplains of His Holiness, when wearing a cassock with coloured trim. A black watered-silk fascia is permitted for priests attached to the papal household, a purple watered-silk fascia for bishops attached to the papal household (for example, Apostolic Nuncios), and a scarlet watered-silk fascia for cardinals. The Pope wears a white watered-silk fascia, sometimes with his coat of arms on the ends. In choir dress, chaplains of His Holiness wear their purple-trimmed black cassocks with a cotta, but bishops, protonotaries apostolic, and honorary prelates use (with a cotta or, in the case of bishops, a rochet and mozzetta) cassocks that are fully purple (this purple corresponds more closely with a Roman purple and is approximated as fuchsia) with scarlet trim, while those of cardinals are fully scarlet with scarlet trim. Cardinals have the additional distinction of having both choir cassock sleeves and the fascia made of scarlet watered-silk. The cut of the choir cassock is still a Roman-cut or
