Using this shirt is super easy. Just put it on like any other shirt and you're ready to go for a casual day out. It can be paired with jeans or shorts for a laid - back look. When it comes to washing, you can machine - wash it in cold water with similar colors to keep the geometric pattern looking fresh. Avoid using harsh detergents as they may damage the fabric. After washing, tumble dry on low heat or hang it to dry. Before storing, make sure it's completely dry to prevent any mold or mildew. And always check the size chart carefully before buying to ensure you get the right fit for you.
