In its liturgical use in the West, this garment was folded up from the sides to leave the hands free. Strings were sometimes used to assist in this task, and the deacon could help the priest in folding up the sides of the vestment. Beginning in the 13th century, there was a tendency to shorten the sides a little. In the course of the 15th and 16th centuries, the chasuble took something like its modern form, in which the sides of the vestment no longer reach to the ankle but only, at most, to the wrist, making folding unnecessary.
