Color is excellent
Color: Dark Green, Size: X-Large
The fit overall is good. The arms are a little big but fits well everywhere else. Love the color.

Solid Basic Dress Shirt With a Slightly Small Fit
Color: Grey, Size: XX-Large
This shirt is pretty decent overall for the price. The material is on the thinner side, but thankfully it doesn’t have that overly shiny look that a lot of cheaper dress shirts tend to have. It still looks fairly clean and presentable, and it works well for business casual wear or occasions where you just need a simple button-down that looks put together.
Fit-wise, I’d say it runs slightly small. It’s not dramatically off, but if you’re between sizes or prefer a little extra room, sizing up might be a good idea. Other than that, it’s a solid basic shirt that gets the job done without looking cheap.

Order a size up
Color: Black, Size: X-Large
Whatever their size chart says order a size up and it will fit perfect. The size chat suggests a large for me. I read some reviews and ordered extra large and it fits perfect.
