This formal men's suit is perfect for weddings. To wear it, first put on the jacket and button it up according to the single-breasted closure. Then, zip up the pants with the zipper fly. Make sure to check the size chart before purchasing as different suppliers and brands may have different size standards. If it's an Asian size, it's better to choose a bigger size. When it comes to maintenance, since it's made of polyester, it's relatively easy to care for. You can machine wash it on a gentle cycle with cold water and mild detergent. Hang it to dry to keep its shape. Avoid ironing at high temperatures to prevent damage to the fabric. With proper care, this suit will look great for many events to come.
