How to use these t-shirts is simple - just put them on and look great! When it's time to clean them, remember to machine wash them cold and inside out with clothes of similar colors. Only use non - chlorine bleach if necessary. After washing, hanging them to dry will give the best results, but you can also tumble dry on cool or low heat. Don't use fabric softener because it can make the colors fade. And please don't iron or dry clean these shirts to keep them in good condition.
