Regular care and maintenance will help keep cotton in its original condition for longer. Proper cleaning and maintenance will help keep your cotton item looking its best. We would advise checking each individual care label before attempting to clean. As cotton lacks natural anti-bacterial and odor-resistant properties, it requires more frequent washing. It’s simple to care for too, and most pieces can be washed in the machine at 30°C unless specified otherwise on the care label. Choosing a cycle with a moderate temperature instead of hot will help prevent damage and shrinkage to cotton and cotton-blend garments. Avoid tumble drying to allow cotton to air dry flat away from direct sunlight instead. Discover the latest selection of PS by Paul Smith underwear at Lyst. Shop today.
