To use these women's t-shirts and premium t-shirts, simply put them on and enjoy their comfort and style. When it comes to washing, turn them inside out and machine wash in cold water with clothes of similar colors. Only use non - chlorine bleach if needed. After washing, you can hang them to dry for the best results, or you can use the tumble dryer on a cool or low - heat setting. But be careful, 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.
