What is a "collar"?

A collar is a part of a garment that is fastened around the neck and often frames the face. It can be a separate piece, attached to the garment, or built into the design of the clothing. Collars come in many styles, such as flat, stand-up, mandarin, pointed, and Peter Pan. They can be stiffened with interfacing or left soft, depending on the desired look. Collars can be found on a variety of garments, including shirts, blouses, jackets, and dresses, and can add structure and interest to an outfit. The type of collar used on a garment can also contribute to the overall style and formality of the garment.
