Honestly, I was expecting better quality, but I guess it is reasonable for the price. One thing I noticed is that the brand does not seem to have consistency in the materials they use. I was expecting to receive the same quality and feel that I got with the first shirt I purchased, but unfortunately, that was not the case with this black shirt.

Not what was expected

Color: Black, Size: X-Large

The shirt did not match the image on the website. While it is a button-down collar, the buttons are concealed, rather than exposed, and the material is polyester or nylon, giving the shirt a plastic sheen, which I do not like. The image on the website showed exposed buttons, and with tremors in my hands, exposed buttons are hard enough to secure.
