Nice shirt, excellent quality, nice cloth and buttons. No pockets A+
Fit Type: Regular Fit, Color: White, Size: Large
Nice quality shirt cut a little small. The shirt kind of needs to be pressed before wearing however at this price point and quality its a buy!

Comparable to high end mens shops!
Fit Type: Regular Fit, Color: Blue, Size: Large
Beautiful, heavy blue Oxford comparable to upper end mens store at 75% less! Full cut, great for casual wear or sending out for professional starching. Downside, no pocket, but I had mine monogramed wear the pocket would be and it looks like an expensive dress shirt. I bought more (with pockets) in blue & white

Heavier fabric, very durable
Fit Type: Regular Fit, Color: Grey, Size: Large
3 stars. Pretty nice shirt but the fabric is a bit firmer than i like. I iron it when i usually wear it so that it looks half decent since wrinkle resistance is low or poor. I usually have to use a higher setting on the fabric since the material is thick making it alot heavier. Overall great for the lower end cost, anything that beats it would probably be double the price. I work in a cubicle so this works well for me, a simple shirt, with a simple color.
