To use these women's T-shirts and premium T-shirts, simply put them on and enjoy their comfort. When it's time to clean them, remember to machine wash in cold water, turning them inside out and washing with similar colors. Only use non - chlorine bleach if necessary. For the best look, hang them to dry after washing, but you can also tumble dry on a cool or low - heat setting. Be careful not to use fabric softener as it can make the colors fade. And don't try to iron or dry clean these shirts to keep them in good condition.
