The cuff is a detail that finishes the sleeve at the wrist, giving it a tidy, complete appearance. A cuff can be functional (fastening with a button or cufflink to adjust the sleeve width) and decorative (a turn-back, trim, contrasting fabric). In a classic shirt it is the cuff that is one of the details betraying the quality of cut and cloth. Historically lace and embroidered cuffs were a sign of luxury, and cufflinks turned the fastening of a cuff into a separate object of jewellery art. In the folk shirt the cuffs were often covered with embroidery continuing the collar. The cuff frames the hand and, like the collar, becomes a visible zone for accent and decoration.
