Very well made Oxford casual shirts.
Size: X-Large, Color: Sky Blue
I've ordered 8 of these Button-down collared, long sleeved Oxford shirts in eight different colors. I'm 6', weigh 195. And have a 44" chest and fairly broad shoulders. The XL give me ample room, plenty of shirt tail to tuck in. And are well made. The shirts have a nice soft feeling to them. If you wash them with like items, and dry them likewise, taking them out before the cycle ends and hanging them. You won't have a single wrinkle. The shirts are true to color, and true to size if you follow the size guideline. These are not tailor fit, but regular fit shirts. Fabric quality seems very durable and well made. There is no smell when receiving the shirts. No more so than buying a shirt at a retail store. They do come in a vacuum bag. The shirts are a little heavier than a poplin shirt and can be worn year-round. These are great casual shirts for jeans and a sport coat, or slacks. I like the quality and the colors. I also like the thickness of the shirts. All of the shirts I've bought, black, blue, etc, have white buttons. Which makes them more of a casual shirt. But well worth the price.

Good quality
Size: 3X-Large, Color: White
The shirt fit great! True to size. Only issue for me, it would have been nice if it was longer to tuck in.

Good Material Thickness and Comfortable
Size: XX-Large, Color: Blakc
I picked up the J.VER Men’s Oxford Shirt, and it turned out to be a solid choice. The seam quality is clean and consistent, with no loose threads or uneven stitching. The material thickness is right where it should be for an oxford. It feels sturdy without being stiff.
There was no strong smell out of the package, which is always a plus. After a quick wash, it was ready to wear. The stretchiness is subtle but helpful. It gives the shirt some flexibility without changing the classic look.
The softness surprised me. It feels comfortable on the skin and stays that way through the day. Overall comfort is great, whether you’re wearing it for work or a casual night out.
A clean, comfortable shirt that fits well and looks good.
