Traditional Grown Man Shirt
Size: Large, Color: Light Grey Vertical Stripe
Great cotton, classically-style button down shirt for guys not wanting anything slim fit, this shirt size is legitimate. It’s a nice heavyweight cotton shirt. I don’t think I’d say it was wrinkle resistant but it doesn’t take much effort to press this garment.

Softer and Larger than Expected
I was a bit wary of this shirt because I had only purchased 100% cotton ones in the past. My first impression out of the package was how soft the material felt. I was very impressed because it usually takes many washings before oxford cloth shirts get that soft. When I put it on, I discovered that there was no noticeable difference made with the small amount of stretch fabric woven into the shirt. I suspect that there would be some give if I wore the shirt as a tight fit, but I prefer my shirts loose, so it wasn't an issue.
I found that the shirt was larger than other same sized shirts I've received from Amazon in the past--bigger is better than smaller, but if you are looking for a close fit, you will want to be conservative in the size you order. I didn't realize until I'd been wearing it for a while that it lacks a pocket, I went to put my glasses in my shirt pocket and there wasn't one!

True oxford, comfortable, good fit, iron
Size: Large, Color: Light Grey
Great clean-cut, casual shirt. Material is thick as you should expect for a true oxford shirt, even with the stretch/elastane. Good fit, sleeves arent overly long. You’ll probably need to iron it. Overall very happy with purchase.

Amazon Essentials competes well with other store brands
Very Nice and comfortable shirt, on the thicker side and is slightly blue, baby blue perfect in fall winter might be a little thick for summer. the buttons and stitching all seem well done for the price. The size was true and fit great, the big tall size worked great, the shirt does not seem to wrinkle easily since it is thicker

Really great shirt, really thick material
An unexpected pleasant surprise. Really nice quality, minimal shrinkage, and very few wrinkles out of the dryer. Nice, comfortable fit, and for big-but-not-tall guys, the fitment is very presentable. Sleeves aren't crazy long, and the shirt itself isn't so long that you feel like you're wearing a dress.
These aren't complaints, but I do want to share two notes that were important to me:
1. If you want a breast pocket, be sure to select the right shirt. There are two different versions, and it's not particularly obvious which is which.
2. The material is thick. Really thick. So the shirt is pretty heavy, and it doesn't breathe very well. For me, this is unquestionably a winter shirt. If, like me, you tend to run a bit warm, this shirt can make you feel like you're wearing a parka.
