To use these women's T-shirts and premium 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, hanging them to dry is the best option, but you can also tumble dry on cool or low heat. Remember, fabric softener can make the colors fade, so don't use it. Also, avoid ironing and dry cleaning these shirts to keep them in good condition.
