Cotton t-shirts need to be cared for properly to ensure they stay looking their best. To keep cotton looking its best we would advise following the instructions on the label carefully to ensure the longevity of each cotton piece. Cotton is not only comfortable, but easy to care for too. 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. If the cotton item is coloured, turn inside out before cleaning. Once washed, gently stretch garments back into shape and always air dry flat away from direct heat.
