The fit is pretty good, it's acceptable.
Color: Navy Blue, Size: X-Large
Very good fit. The sleeves are long enough, I guess. I'll be rolling them up anyway. I would like it to be a tad bit longer though for tucking in. Other than that it feels nice and lightweight, can't wait to wash it so I can use it for going out.
