Cotton clothing is an investment, and it pays to care for it properly. We recommend checking each individual care label before attempting to clean. Cotton is a popular material that is used in a wide range of garments due to its softness and durability, and is also easy to care for. Generally, cotton should be hand or machine washed at 30°C or below. As darker dyes can ruin lighter fabrics, it is recommended to wash dark and light colours separately inside out. Always air dry flat if possible, and give cotton items a gentle stretch to get them back into shape when they first come out of the wash.
