Might buy a couple more.
Color: Demin Blue, Size: Large
In the process of losing weight and needed a nice looking shirt for work without spending a lot of money on something that will only fit for a few months. This did the trick! Fits well, looks nice, and at a great price.

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.
