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.

Great Value from Amazon Essentials
I can’t believe the quality of this shirt given the low price I paid for it. It fits perfectly, looks impressive, and is very comfortable. The shirt has survived two washes so far and looks as good as new. I couldn’t be more satisfied with this purchase.

Too large, length too long
Size: Medium, Color: Light Grey Vertical Stripe
Runs large, and the length is far too long to wear untucked like in the photos. Always wear a Medium, this fits like a Large. Length of shirt is long and obviously made to be tucked in. You would look ridiculous if you left it untucked. Dont understand why companies still insist on designing shirt to be tucked in when most people dont wear it like that these days
