In general it has retained the medieval form more closely than the Roman rochet and more resembles the alb, insofar as it is of plain, very fine linen, and reaches almost to the feet. Where the Roman rochet is descended from the surplice, the rochet in its Anglican form is equal to that of the earlier style albs worn by priests. The main modifications have been in the (usually) baggy 'lawn' sleeves that are gathered at the wrists with a band of black or scarlet cloth. At the time of the Reformation these were still narrow, though already showing a tendency to expand. The portrait of Archbishop Warham at Lambeth, for instance, shows a rochet with fairly wide sleeves narrowing towards the wrists, where they are confined by fur cuffs. This fashion continued until, in the 17th century, the sleeves became much fuller; only in the 18th century did they develop into the familiar exaggerated balloon shape, confined at the wrists by a ribbon, beyond which a ruffle projected. About the same period, too, arose the custom of making the rochet sleeveless and attaching the lawn sleeves to the chimere. This remained the fashion most of the 19th century, but there has since been a tendency to revert to the earlier less exaggerated form, and the sleeves have been reattached to the rochet. The ribbon by which the wrist is confined is red, except when conducting or participating in a formal, public funeral (e.g. of a head of state), when it is black.
