These men's shirts from the Call of Christmas collection are easy to use. Just put them on and look great! When it's time to clean them, machine wash them cold, turning them inside out and washing with similar colors. Only use non - chlorine bleach if necessary. After washing, hanging them to dry is the best way, but you can also use the tumble dryer on cool or low heat. 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.
