To use these women's t-shirts, simply put them on and enjoy their comfort. When it's time to wash, machine wash them cold and turn them inside out to protect the fabric. Wash with similar colors to prevent color bleeding. Only use non - chlorine bleach if really needed. After washing, you can hang them to dry for the best results, or tumble dry on cool/low heat. Remember, fabric softener can make the colors fade, so it's better not to use it. And don't try to iron or dry clean these shirts, as it might damage the material.
