Rochet
A vestment of white linen or similar material which replaced the alb and which in time came to be used only by bishops. Early American bishops found the huge balloon sleeves difficult both to launder and to carry, so the rochet was sleeveless, and the sleeves were tacked lightly to the chimere. Styles have changed in recent years, and many rochets now resemble albs.
