This 'Winter Moon' long sleeve t - shirt is super easy to use. Just put it on and enjoy its comfort throughout the day. When it comes to cleaning, remember to machine wash it cold and turn it inside out. Wash it with clothes of similar colors to prevent color bleeding. Only use non - chlorine bleach if it really needs it. After washing, hanging it to dry is the best way to keep its shape. But if you're in a hurry, you can tumble dry it on a cool or low - heat setting. Stay away from fabric softeners as they can fade the shirt. And never iron or dry clean this t - shirt to keep it in good condition for a long time.
