To use this sweatshirt, simply put it on and enjoy the cozy warmth it provides. You can wear it on casual days out, at home while relaxing, or for a laid - back gathering. When it comes to maintenance, it's best to wash it in cold water with like colors. Avoid using bleach as it may damage the fabric and the graphic design. Tumble dry on low to keep it in good shape. Since it's made to order, be patient during the 7 - 10 business days processing time. Also, the spandex in the collar, cuffs, and waistband gives it a stretchy fit, but don't pull it too hard to maintain its shape.
