Good fit, crisp, washed well.
Size: Large, Color: Burgundy
This is the perfect short-sleeved version of their dressier long-sleeve Oxford button-down. Fits my newly downsized, 160-pound, 5'9" shape just right. (At 170, this might be too snug, if I put the full extra ten in my belly, which is where it always seems to go.) For appearance's sake, I prefer the long-sleeve and just roll it up on a hot day. But, sometimes, you really want the airiness and height of a genuine short-sleeve shirt. If you're OCD about a consistent look (which, sometimes, I am), and you like their long-sleeve version, having a few of these in your closet makes life easy on a hot day.

Great shirt but won’t work if your slim cut.
Size: Large, Color: Dull Pink
Fabric is nice and looks of good quality, just is a bit wide in the torso, so it doesn’t fit my slim fit husband. If you wear slim fit dress shirts I would likely say this shirt will be boxy on you in the waste. Good price if it works for you and comes in so many color options!

No negatives about these shirts.
Size: XX-Large, Color: Light Green
Can't say enough good things about these shirts. I have purchased several colors of these shirts and they fit wonderfully. I have a belly so button down shirts that actually fit are hard to find. They are either too big across the shoulders to fit my belly or just too tight around my belly. These fit and look create and i will buy them again as needed.
