This cool purple 3D galaxy pattern hoodie is super easy to use. Just put it on and enjoy the comfort and style. Whether you're going out for a walk or relaxing at home, it's a great choice. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal one because of the international sizing standard. If you're a woman, you can pick a smaller size. For washing, use cold water on a gentle cycle with mild detergent in the machine, then hang it up to dry. Keep in mind that the color you see on your screen might be a bit different from the actual hoodie, and there could be a small measurement difference due to hand - measuring.
