A collar is a band or strap that encircles the neck of a garment, often found on shirts, blouses, and jackets. It serves both functional and decorative purposes, helping to keep the garment in place while adding style. Collars can come in various shapes and sizes, such as pointed, mandarin, or Peter Pan. In addition to clothing, collars are commonly associated with pets, particularly dogs and cats. These collars are typically made of fabric or leather and can hold identification tags, ensuring pets can be returned if lost. Some collars also feature bells or other accessories for added functionality.
