These men's suit pants are great for spring and autumn. Just put them on like you would any regular pants. When it comes to choosing the right size, remember Asian sizes are smaller, so pick a larger size if you're in between. Check the size chart before buying, and if you're not sure, ask our customer service. As for color, it might look a bit different on your screen compared to the real pants. To keep them in good shape, follow the care instructions on the label. Usually, polyester pants can be machine - washed on a gentle cycle. Hang them to dry to avoid shrinking or wrinkling. And that's all you need to know to enjoy your new pants!
