A duster coat is a lightweight, long coat traditionally made from cotton or linen. It was originally designed for horse riders to protect their clothing from dust and dirt while traveling. Duster coats typically feature a loose fit, a button or tie closure, and may have a belt to cinch the waist. Today, duster coats are popular fashion items, often worn as stylish outerwear. They come in various colors and patterns, making them versatile for different occasions. Many people pair them with casual outfits or use them to add a layer of sophistication to their look, similar to how one might wear a trench coat.
