Open Shirt
This is almost exactly how I enjoy seeing guys dressed (or at least one of the ways). I do notice that his shirt tails are not tucked in but otherwise I enjoy this one's appearance very much with his shirt collar showing outside his jacket and his top buttons undone. Many times I wonder if he had on a tie before losening up. This is how guys in the USA used to dress duing the 1970s and still how many Latin men wear their clothes to this day.
