To use these women's shirts, simply put them on and enjoy their comfort. When it's time to wash, machine wash them cold inside out with similar colors. Only use non - chlorine bleach if necessary. After washing, it's best to hang them to dry, but you can also tumble dry on cool or low heat. Don't use fabric softener because it can make the colors fade. And remember, don't iron or dry clean these shirts to keep them in good condition.
