These men's business trousers are a great addition to your wardrobe. To wear them, simply put them on like any regular pair of pants. When choosing a size, remember to check the size chart as different suppliers and brands may have unique sizing. If it's an Asian size, opt for a bigger size. For maintenance, these trousers made of polyester, spandex, and viscose can usually be machine - washed on a gentle cycle. Hang them to dry to keep their shape. Iron them on a low - heat setting to get rid of any wrinkles and keep them looking sharp for your business meetings or formal occasions.
