To wear this Charente blazer, you can simply button it up over a striped top and jeans for a casual yet stylish look. Or, pair it with a dress shirt and dress pants for a more formal occasion. When it comes to buttons, you can choose to button all of them or just the top ones according to your preference. As for maintenance, dry clean it to keep the wool in good condition. Avoid exposing it to direct sunlight for a long time to prevent color fading. And when not in use, hang it on a sturdy hanger to maintain its shape.
