A local brand called Mirto. Got it on great discount. The fabric is something I had never heard about before, it says "lana italiana by Bottoli" and is undyed.
Shirt shoulders are great. I don't even feel like I'm wearing a jacket at all. I'd have liked the jacket better if it had padded lapels and higher armholes, but the lack of any canvas is something different and welcome, too.
It looks great. My shoulders seem to not have much luck when it comes to off the rack SCs but unstructured ones just seem to look better on me. I am going to see if Mirto is available anywhere online. Thanks!
