Using this black polyester blazer is super easy. Just put it on over your shirt or top, and you're ready to go for any casual or formal event. When it comes to care, it's best to follow the washing instructions on the label. Usually, a gentle machine wash in cold water should be fine. Avoid using harsh detergents as they may damage the fabric. Hang it up to dry instead of putting it in the dryer to keep its shape. When not in use, store it in a cool, dry place, preferably on a hanger to prevent wrinkles. And always double - check the size chart before buying to ensure the perfect fit.
