Wear this shirt right out of the box.  Any creases melt away.  While I would agree that cotton may be comfortable but it looks like trash half way through the day.  If you travel for business or you have an infrequent need for a shirt out of the closet to look freshly pressed, then these are very good for that.  The fit is true.  The only aspect which could be made better would be to add some stretch or spandex into the shirt for an even more fitted look.
