Using this blazer is easy. Just put it on over your shirt or top, fasten the single button, and you're ready to go. It's suitable for many occasions, like business meetings or casual outings. When it comes to maintenance, it's recommended to dry - clean it to keep the fabric in good condition. Avoid exposing it to direct sunlight for a long time to prevent color fading. Also, be careful not to snag the fabric patchwork decoration. Check the size chart carefully before buying to ensure you get the right fit, as different suppliers may have different sizing standards.
