To use these t-shirts, just put them on and show off your style! When it's time to wash, use cold water and turn the shirts inside out. Wash them with similar colors to avoid color mixing. Only use non - chlorine bleach if necessary. After washing, you can hang them to dry for the best look, or you can tumble dry on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. And don't iron or dry clean these shirts to keep them in good condition.
