To use this sweatshirt, simply put it on like any other top. It's great for casual outings, lounging at home, or layering up in cold weather. Since it's made to order, be patient during the 7 - 10 business day processing time. When it comes to maintenance, machine - wash it in cold water with like colors to keep the colors vibrant and the fabric in good shape. Tumble dry on low to avoid shrinking. Don't iron directly over the graphic to prevent damage to the heat - transfer design. Also, try not to pull or tug too hard on the fabric to maintain its shape and the integrity of the stitching.
