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