How to use: Just put on your favorite T - shirt and rock your day! When it comes to washing, make sure to turn the shirt inside out and wash it in cold water with similar colors. Only use non - chlorine bleach if it's really dirty. For drying, hanging is the best way to keep the shirt in good shape, but you can also use the tumble dryer on a cool or low - heat setting. Remember, fabric softener can fade the colors, so skip it. And don't try to iron or dry clean these shirts, as it might damage them.
