I think there is an outside chance that it might end pretty well even on the first attempt. I have not used 5*, but a repeating refrain is that you have to be REALLY detailed with them (pictures, drawings, measurements, following up) to get a good result. How about sending them a jacket that is oversized exactly like the one you want (in different style, of course), and asking them to use these measurements to make the exact jacket from the X-files pics? Given your relative inexperience in jackets measurements it might be the best chance to get it close-to-right the first time. I will let those who used 5* opine on whether that is a good strategy. Of course assuming that the OP did not leave the thread in a huff, clearly misunderstanding @Peacoat comment.
