To wear these t-shirts, just slip them on and you're good to go! When it's time to clean, machine wash them cold and turn them inside out. Wash with clothes of similar colors to prevent color bleeding. Only use non - chlorine bleach if really necessary. After washing, you can either hang them to dry for the best results or tumble dry on a cool or low - heat setting. But be careful not to use fabric softener because it might make the colors fade. Also, don't try to iron or dry clean these t - shirts as it can damage the fabric.
