I love this shirt - the fabric is "old school cotton" great. I would say that because of the old school cotton feel of the shirt (it is not stretchy, like many man-made shirts), you might order a size up and I trimmed out the collar to give it a little more open feel. I bought the same shirt for a guy friend of mine and he's very happy with the cozy fit. I love the design, which is centered well for any size human...and the subtle tie dye is VERY happy indeed! I'd buy more of these for sure...
