A peacoat is a classic outerwear garment typically made from heavy wool. It features a double-breasted front, wide lapels, and often has large buttons. Originally worn by sailors in the navy, the peacoat is designed to provide warmth and protection against wind and cold weather. The peacoat is usually hip-length and can come in various colors, though navy blue is the most traditional. It is a versatile piece that can be dressed up or down, making it popular for both casual and formal occasions. The timeless design has kept it in style for many years.
