This sweater is super easy to wear. Just pull it on over your head and you're good to go. You can pair it with a simple tee and jeans for a stylish casual look. When it comes to washing, it's best to follow the care label instructions. Usually, you can machine - wash it on a gentle cycle with cold water. Avoid using bleach as it may damage the 3D print. Hang it to dry to keep its shape. As for sizing, always check the size chart carefully since different suppliers and brands have different sizing. If you're in doubt, it's better to choose a slightly larger size for a more comfortable fit.
