A cuff is an extra layer of fabric at the lower edge of the sleeve of a garment (shirt, coat, etc.) covering the arm, at the wrist. The function of turned-back cuffs is to protect the cloth of the garment from fraying, and, when frayed, to allow the cuffs to be readily repaired or replaced, without changing the garment. Cuffs are made by turning back (folding) the material, or a separate band of material can be sewn on, or worn separately, attached either by buttons or studs. A cuff may display an ornamental border or have lace or some other trimming. In US usage, the word trouser cuffs refers to the folded, finished bottoms of the legs of a pair of trousers.
Except on casual attire, shirt cuffs are generally divided down one edge and then fastened together, so they can let a hand through and then fit more snugly around the wrist. Some sweaters and athletic garments (both tops and pants) have cuffs that either contain elastic or are woven so as to stretch around a hand or foot and still fit snugly, not accomplishing the same purpose.
