Using these T-shirts is as easy as just putting them on! When it comes to washing, make sure to turn them inside out and wash them in cold water with similar colored clothes. Only use non - chlorine bleach if necessary. After washing, hanging them to dry is the best way to keep them in good shape, but you can also tumble dry on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so don't use it. And never iron or dry clean these shirts. This way, you can enjoy your 'Dolls and Killers' T - shirts for a long time.
