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 , 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.
