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. Peacoats are usually hip-length and can come in various colors, though navy blue is the most traditional. They are versatile and can be dressed up or down, making them a popular choice for both casual and formal occasions. The timeless style of a peacoat has kept it in fashion for many years.
