What is a "sleeve"?

A sleeve is a component of a garment that covers the arm from the shoulder to the wrist. It can come in different lengths, shapes, and styles depending on the type of clothing. Sleeves can be set-in or raglan, and they can also be fitted or loose. The cuffs or openings of the sleeves may also have different features like buttons, zippers, or elastic bands. The sleeves of a garment play an important role in its overall design and functionality, as they can affect how comfortable, warm, and flexible the clothing is for the wearer.
