the sopra (or supra) vest is a long drape of thin, black cloth that buttons close down the neck and to one side, falling to the ankles and cut so as to entirely cover the body. it is similar to a cassock, though it is actually derived from the "supra vesta" a black surcoat worn in the mid 13th century by the knights of st. john. confrères in grade i have a plain, white, 300mm diameter maltese cross on their sopra vests, while members of grades ii and iii, plus chaplains, have a plain garment, though the wearer's order of st. john medallion hangs outside the vest, 152mm below the collar. clerical inductees of the order may, when officiating, wear over their cassock and surplice a tippet of black with red lining, edging, and buttons, a 76mm wide star worn on the left breast and the accordant badge suspended at the neck. when full mantles and sopra vests are worn a black velvet tudor style hat is included.
