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 inside out with clothes of similar colors. Only use non - chlorine bleach if necessary. After washing, hanging them to dry will give the best results, but you can also tumble dry on cool or low heat. Remember, using fabric softener might make the colors fade. Also, don't iron or dry clean these shirts to keep them in good condition.
