To use these women's t-shirts, simply put them on and enjoy their comfort. When it's time to clean them, machine wash them cold and turn them inside out. Wash with similar colors and only use non - chlorine bleach if needed. After washing, you can hang them to dry for the best results or tumble dry on cool/low heat. Remember, fabric softener can make the colors fade, so avoid using it. Also, don't iron or dry clean these shirts to keep them in good condition.
