To use these women's t-shirts, simply put them on and enjoy the comfort. When it's time to clean them, machine wash them cold, turning them inside out and washing with like 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. Remember, fabric softener might make the colors fade, so skip it. And don't iron or dry clean these shirts to keep them in good condition.
