Here's how to make the most of your Digital Phoenix Tully University sweatshirt. First, pick the right size from S to 4XL. When it comes to washing, turn it inside out and wash it in cold water with similar colors. Only use non - chlorine bleach if it gets really dirty. After washing, hanging it to dry is the best way to keep its shape, but you can also use the tumble dryer on a cool or low - heat setting. Just remember, fabric softener can make the colors fade, so skip it. And never iron or dry clean this sweatshirt to keep it looking great for a long time.
