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. We recommend washing at a cool temperature that is no more than 30°C, and then gently reshaping as soon as it comes out of the wash. Cotton pieces can then be gently stretched to restore the original shape. Air dry cotton naturally. Shop the latest selection of sweats for women from Reformation today.
