Thanks everyone for your feedback on the fit! Unfortunately I just can't quite warm up to it on my frame, at least in the bottom half. I've seen a few CPO fits on the forum that are slightly more fitted through the torso and I just love the look. Seeing the measurements on the large, I think that would have been perfect for me. It is such a great shirt!
jeanwerk.ch shows a size large in stock, but they sadly do not appear to ship to the US. If anyone is in Switzerland and has any interest to a proxy purchase on my behalf, I'll certainly compensate you for the effort, haha!
