This hoodie is super easy to use. Just slip it on and enjoy the comfort and style it brings. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size because of the difference between international and US sizing standards. For maintenance, you can simply toss it in the washing machine. Use cold water, select the gentle cycle, and add a mild detergent. After the wash, hang it up to dry. Also, keep in mind that the color you see on your screen might be a bit different from the actual product, and there could be a small measurement error because it's hand - measured.
