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