Using this jacket is super easy. Just put it on like any other jacket and fasten the single button. You can wear it over a t - shirt during the day or layer it over a sweater in colder weather. When it comes to cleaning, check the care label on the jacket. Usually, polyester jackets can be machine - washed on a gentle cycle with cold water. Avoid using harsh detergents as they may damage the embroidery. After washing, let it air - dry to maintain its shape. When storing, hang it on a hanger in a cool, dry place to prevent wrinkles and keep it looking its best. Always double - check the size chart before buying to ensure a proper fit, as different brands may vary in sizing.
