Using these women's T - shirts and Premium T - shirts is as simple as putting them on. When it comes to washing, make sure to turn them inside out and wash them in cold water with similar colors. Only use non - chlorine bleach if you really need to. After washing, hanging them to dry will give the best results, but you can also use the tumble dry function on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so it's better to skip it. Also, do not iron or dry clean these shirts to keep them in good condition for a long time.
