An overcoat is a type of outer garment designed to be worn over other clothing for warmth and protection against cold weather. Typically made from heavy fabrics like wool or cashmere, overcoats are longer than regular jackets, often reaching below the knee. They come in various styles, including trench coats, pea coats, and chesterfield coats, each offering different features and aesthetics. Overcoats are usually worn in formal or casual settings and can be paired with various outfits. They often include elements like buttons, belts, and pockets, enhancing both functionality and style. Many people choose overcoats for their versatility and ability to keep warm during winter months.
