To wear these trousers, simply pull them on. They're great for a casual or polished daytime look. You can pair them with a tweed blazer as mentioned for a refined style. When it comes to maintenance, these trousers are wrinkle-resistant, so they don't need too much special care. But if they do get wrinkled, a gentle ironing on a low - heat setting should do the trick. Just be careful not to use high heat as it might damage the fabric's stretchy quality.
