To wear these t - shirts, just pick your size and put them on like any regular shirt. They'll fit you comfortably whether you're going out or staying in. When it's time to clean them, machine wash them cold and turn them inside out to protect the color. Wash them with clothes of similar colors. If they get dirty, use non - chlorine bleach. After washing, it's best to hang them to dry to keep their shape. But if you're in a hurry, you can use the cool or low - heat setting on your dryer. Don't use fabric softener as it might make the colors fade. And remember, don't iron or dry clean these shirts to keep them in great condition.
