To wear this sequined trilby fedora hat, simply place it on your head. It's a one - size - fits - all hat, so it should sit comfortably without any adjustments. When you're not using it, store it in a cool, dry place to prevent damage to the sequins and the fabric. To clean it, use a soft brush to gently remove any dust or debris. Avoid getting it wet as it might damage the sequins and affect the hat's shape. If it gets really dirty, take it to a professional hat cleaner.
