The amice is the first garment to be put on by a priest. It is worn on the head, while he offers up prayers and intercessions, and then he continues to dress. After the alb is put on, the amice is pushed off his head and worn around his neck as a collar. The long cords of the amice are then tied around the alb under the arms, crossed around the back, and brought back to the front to be tied. All this being said, there are instances when the amice is kept upon the head for practical reasons: such as warmth during a processional or in a particularly drafty church.
