Using this hoodie is easy - just put it on and enjoy its stylish look. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size because our international sizing is smaller than the USA standard. Check the size chart for exact measurements. For washing, use cold water on a gentle cycle with mild detergent. Don't forget to hang it to dry. And keep in mind that the color on your screen might be a bit different from the real hoodie due to monitor settings.
