To wear this Japanese Ice Cream crewneck sweatshirt, simply put it on like any other sweatshirt. It's great for casual outings or just lounging at home. When it comes to washing, make sure to turn it inside out and wash it in cold water with clothes of similar colors. If it gets dirty and needs bleaching, only use non - chlorine bleach. After washing, hanging it to dry will keep it in the best shape, but you can also tumble dry it on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean this sweatshirt to avoid any damage.
