Extend the lifespan of cotton t-shirts by years with proper care and maintenance. We suggest always checking the item’s care label before washing. Cotton is not only comfortable, but easy to care for too. To care for your cotton pieces properly, we recommend pre-treating any stains by dampening the affected area with cold water and then applying a stain remover. As heat can often cause cotton to shrink, hand or machine washing at a temperature of 30°C or below is preferred. Once clean, allow to air dry instead of using the tumble dryer. Remove any wrinkles and creases by ironing inside out on a low heat when cotton is still slightly damp, or use steam. Everyone should have Marnit-shirts in their wardrobe. Shop our edit today.
