How to use: Simply put on your 'Yeah, I Know' sweatshirt and flaunt the unique design. It's great for casual outings or relaxing at home. Care tips: When it's time to clean, machine wash it cold inside out with clothes of the same color. Only use non - chlorine bleach if there are stains. Hang it to dry for the best look, but you can also tumble dry on cool or low heat. Avoid using fabric softener as it can fade the colors. And remember, don't iron or dry clean this sweatshirt to keep it in top shape.
