Failure at every step
Item sent was wrong size, missing pieces and used! Not happy. Thankfully Amazon made it right because Coofandy dropped the ball completely. Think twice before ordering from this vendor.

Great shirt for Price
Color: White, Size: Large
Seem to fit true to size and long enough. I cannot stand dress shirts that are too short on the sides and become untucked. I am also getting these embroidered with a company logo to turn into work shirts. I like the oxford feel, buttons are tight fit, arm length is hair long for me (5'11") - but for the fit they fine. I purchased four of these, all were consistent with one another, no surprises.

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.
