Here's how to get the most out of your 'A Very Shiny Christmas' crewneck sweatshirt. You can wear it for all your Christmas celebrations. When it comes to washing, put it in the machine on a cold setting and turn it inside out. Wash it with clothes of 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. If you're in a hurry, you can tumble dry it on a cool or low - heat setting. Just remember, fabric softener can make the colors fade, so skip it. Also, don't iron or dry clean the sweatshirt to keep it looking great for a long time.
