Looks like a very relaxed fabric...like it is never meant to be buttoned...in a good way. It is hard to tell with this fabric, but how impressed are you with Luxire's ability to nail details and measurements? Would you trust them replicating a "nicer" jacket? Edit: I have used them for shirts, just on the fence about mailing in a jacket. They seem to be improving, but I have been waiting until I feel more comfortable.
