What term is used for garments like coats and jackets?

The term "outerwear" specifically refers to garments that are designed to be worn over other clothing, primarily for protection against the elements or to provide warmth. This category includes items such as coats, jackets, and sometimes even vests and capes. Outerwear is essential in various settings, especially in colder climates where layering is necessary for comfort and style.

In contrast, the other options refer to different categories of clothing. Activewear encompasses clothing designed for physical activity, providing comfort and enhanced performance during exercise. Sleepwear includes garments intended for sleeping, such as pajamas and nightgowns, designed for comfort during rest. Underwear refers to garments worn beneath outer clothing, typically for support and modesty, including items like bras and panties. Thus, outerwear is the correct term to describe coats and jackets.
