This is the second shirt I have ordered in this style, different colors. Perfect shirt to dress up for the office or down for time off. The first shirt I ordered in my true size X-Large, 5'9 180 LBS for reference. It fit a little large, long to be exact. I wear it tucked in and it looks good. This time I sized down to a large and I love this fit! Much more flattering and still very conformable. Always get complements when I wear either shirt.
