A cuff is a layer of fabric at the lower edge of the sleeve of a garment (shirt, coat, jacket, etc.) at the wrist, or at the ankle end of a trouser leg. 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. In the UK, while this usage is now sometimes followed, the traditional term for the turned up trouser hem is 'turnup'. History Between the 15th and 18th centuries, rich men often wore sleeve cuffs ornamented with fine lace. Still today, Catholic clergy have the cuffs of their choir dress ornamented with fine lace. Shirt cuffs 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, accomplishing the same purpose. Divided shirt cuffs are of three kinds, depending on how they fasten: Button cuffs, also called barrel cuffs, have buttonholes on the one side and buttons on the other (sometimes more than one, so that the fit can be adjusted). Link cuffs, which have buttonholes on both sides and are meant to be closed with cufflinks or silk knots. They are most commonly fastened in either the "kissing" style, where the insides of both sides are pressed together, or very unusually with the outer face touching the inner face, as with a button cuff (though this is unorthodox). Link cuffs come in two kinds: Single cuffs, the original linked cuff, are required for white tie and are the more traditional choice for black tie. Also, some traditionalists may wear this style with lounge suits as well. French, or double, cuffs, are twice as long and worn folded back on themselves. French
