To use these women's t-shirts, simply put them on and enjoy their comfort. When it's time to clean, machine wash them cold and turn them inside out. Wash with clothes of similar colors and use non - chlorine bleach only if necessary. After washing, it's best to hang them to dry. If you're in a hurry, you can tumble dry on cool or low heat. Don't use fabric softener because it can make the colors fade. And remember, don't iron or dry clean these shirts to keep them in good condition.
