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.
