An accessory is an item that adds to or enhances the main object, often used in fashion or design. Common examples include jewelry, bags, and belts, which complement clothing and help express personal style. Accessories can also refer to items like phone cases or decorative elements in home decor. In legal terms, an accessory can refer to a person who assists in a crime but is not the main perpetrator. This includes individuals who help plan or facilitate the crime, such as accomplices or aiding and abetting individuals, making them liable for their involvement.
