These trousers are super easy to wear. Just put them on like you would with any other pair of pants and adjust the waist belt to your desired tightness. When it comes to cleaning, it's best to follow the care instructions on the label. Usually, polyester trousers can be machine - washed in cold water on a gentle cycle. Avoid using bleach as it may damage the fabric. For ironing, use a low - heat setting. Also, make sure to check the size chart carefully before purchasing to ensure the perfect fit, as different brands have different sizing standards.
