To use these women's t-shirts, simply put them on and enjoy the comfort. When it's time to clean, machine wash them cold inside out with similar colors. Only use non - chlorine bleach if necessary. For the best look, hang them to dry after washing. You can also use a cool or low - heat setting in the dryer. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these shirts as it might damage them.
