Here's how to get the most out of your 'Sunken Treasure' sweatshirt. First, when it's time to wear it, just slip it on like any regular crewneck sweatshirt. It's designed to fit well in sizes from S to 4XL, so you'll find the perfect fit for you. When it comes to cleaning, always use cold water and turn it inside out. Wash it with clothes of similar colors to avoid color bleeding. Only use non - chlorine bleach if there are stubborn stains. After washing, hanging it to dry is the best way to keep its shape. But if you're in a hurry, you can use the cool or low - heat setting in the dryer. Remember, fabric softener can make the colors fade, so skip it. Also, don't try to iron it or take it to the dry cleaner, as this could damage the fabric and the locker patch on the sweatshirt.
