Nice shirt but size up one to two sizes.
Size: Large, Color: Clay
I love this shirt. it is good quality. I got the clay colored one. I really like it. They do run small. I normally wear a medium. So I got a large. It fits pretty well. It is a tad bit tight, but I am losing weight(145LBS) So far. So it should fit fine in a few weeks. I am 5,2 135Lbs. I probably should have gotten the XL.
