Being only 5'3, shirts can be too long or too big but this one is just right. I wear these shirts under my blouses in the office and they look clean and neat. They are fitted enough that they don't add bulk but they don't squeeze me like a sausage either. The expedition weight vs the mid-weight? If you want to feel warmer (not overly so by any means) get the expedition weight. The feel of this one is a softer texture also. The mid-weight is great also, just a bit shorter through the torso and  the material is different, not as soft and better for fall. Worth the money! Love it!
