To wear this blazer, simply put it on over your shirt or top. You can pair it with jeans for a casual look or dress pants for a more formal occasion. When you're not wearing it, hang it on a hanger to keep its shape. Make sure to check the care label before cleaning. Usually, it's best to dry - clean this polyester blazer to maintain its quality and the integrity of the patchwork design. Always double - check the size chart before purchasing to ensure you get the right fit. And remember, since different suppliers may have different sizing, take your time to pick the size that suits you best.
