To use this sweatshirt, simply put it on like any other top. It's great for casual outings or staying at home on a cold day. When it comes to washing, turn it inside out and use a gentle cycle with cold water to keep the design and fabric in good condition. Avoid using bleach as it may damage the colors. After washing, you can tumble dry on low heat or hang it to dry. This will help maintain the shape and quality of the sweatshirt. Remember, it has a tag - free design, so you won't have any annoying scratching on your skin.
