Very nice shirt for the price
Very nice quality shirt at a great price. Bought it for my son for hoco but he ended up not going so I had to return it. The fit was very comfortable and true to size. It came with cuff links. I would definitely buy it again if we need a dressy shirt for an occasion.

Runs tight
It's a little tight for a 2XL even with the stretch. Nice color, kind of stretchy, nice material, didn't have many wrinkles at all, soft, but was pretty tight.
