A shirt collar is the part of a shirt that encircles the neck and is typically made from the same fabric as the shirt. It serves both functional and decorative purposes, providing structure and style. There are various types of collars, including pointed, spread, and button-down, each offering a different look and feel. Collars can be found on many types of shirts, such as dress shirts, casual shirts, and polo shirts. They can be designed to be stiff or soft, depending on the shirt's intended use. The collar can also influence the overall appearance of an outfit, making it an important element in fashion.
