A cloak is a type of outer garment that is typically worn over the shoulders and drapes down the back. It is often made from heavy fabrics like wool or velvet and can be used for warmth or protection against the elements. Cloaks come in various styles and lengths, and they may have hoods for added coverage. Historically, cloaks have been associated with different cultures and time periods, serving as a symbol of status or authority. In literature and film, characters like Harry Potter often wear cloaks, which can enhance their mysterious or magical qualities.
