Occasionally I see tweedy woolen "suiting" from makers like Scabal and Dormeuil that I think would look good on its own as an odd jacket, but something about the finishing puts me off from going through with it -- like it is has a little bit of a slick, underlying sheen. Is this a property of those makers' predilections or more a function of them being finished as suiting? I expect an odd jacket to be totally matte and non refractive. By the way, when I say slick, I don't mean Italian slick, just the subtle light refraction you see in fine woolens. I guess my question is how much light refraction is considered acceptable in an odd jacket(even if it is a woolen tweed pattern) to avoid the whole orphaned suit jacket thing.
