A long coat is a type of outerwear that extends down to the ankles or below, providing warmth and coverage for the wearer. It can be made from various materials such as wool, leather, denim, or other fabrics, and comes in different styles including double-breasted, single-breasted, peacoat, trench coat, etc., depending on the design and occasion. Long coats are typically worn during colder seasons to keep individuals warm and protected from harsh weather conditions such as rain, snow, or wind.
