This is a fantastic shirt. I wear it as a work shirt but it is cut stylish enough that I can get away with wearing it to casual affairs. The thickness of the denim is similar to a medium flannel shirt so I can wear it on a warm day and not sweat. On cold days I can easily layer up as needed and not feel bulked. It is slim cut so EX large feels like a tailored fit for me. However, there is magically lots of room for body movement while working. There is some room for a large gut, but it's really a slim cowboy cut so if this is a concern you might want to try it on first or buy a bigger size than normal. The 'tall' cut is great for a working guy because it's really tall. There is not going to be any 'plumber's crack' here. To me the shirt has enough of a tailored feel that I wear it to social functions every so often. Once I wore it with a tie to go someplace. My wife wrinkled her nose and said it didn't look toooooo bad. Good enough. That's all I needed to hear. This shirt is part of  my 'default' apparel and I think it will be the same for you.

Update 02/2017; if you are now looking at a Wrangler short sleeve  dark blue denim shirt, that is not what I originally reviewed. My original review was for a long sleeve, light blue denim, Wrangler Authentic Cowboy Cut Western Work Shirt with snap buttons. My review is not for this product.
