The term 'Parts of Shirt Sleeves' can refer to two distinct parts of a shirt sleeve: CUFFS and hems. CUFFS are the folded or pleated fabric at the end of a shirt sleeve, usually with buttons or snaps for closure. They are typically made of a different material than the rest of the shirt sleeve and are designed to provide a snug fit around the wrist. Hems are the bottom edges of the shirt sleeve, which are usually sewn with a double-stitch to prevent fraying. Both CUFFS and hems are important components of a shirt sleeve, as they provide structure and shape to the garment.
