Pants designed to be paired with a sportcoat or matching suit are always tailor made (regardless if they were runway or not). There is a small amount of pants that are designed to stand on their own or be paired with his more casual/runway clothes that are not tailor made.
There might be some differences in construction, but as far as I can tell there is no marked difference (except maybe the factory in where it was created?) in quality.
