To use these women's shirts, just put them on and enjoy their comfort. When it's time to clean them, machine wash cold inside out with clothes of similar colors. Only use non - chlorine bleach if necessary. For the best look, hang them to dry after washing. You can also use a tumble dryer on cool or low heat. But remember, fabric softener can make the colors fade, so don't use it. Also, avoid ironing and dry cleaning these shirts to keep them in good condition.
