Using these Deadly Nightshade women's t-shirts is easy. Just put them on and enjoy the comfort. When it comes to washing, remember to machine wash them cold inside out with 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 with cool or low heat. Don't use fabric softener because it might make the colors fade. And never iron or dry clean these shirts to keep them in good condition.
