A rochet (/ˈrɒtʃət/)[1] is a white vestment generally worn by a Roman Catholic or Anglican bishop in choir dress. It is virtually unknown in Eastern Christianity.[2] The rochet in its Roman form is similar to a surplice, with narrower sleeves and a hem that comes below the knee, and both of which may be made of lace. The Anglican form is a descendant of traditional albs worn by deacons and priests, but with sleeves gathered at the wrists, and nearly as long as the underlying cassock.
The word stems from the Latin rochettum (from the Late Latin roccus, connected to the Old High German roch, roc and the Anglo-Saxon rocc; Dutch koorhemd, rochet, French rochet, German Rochett, Chorkleid, Italian rocchetto, Spanish roquete), which means an ecclesiastical vestment.[2]
