I am 6’ tall and around 140lbs. I ordered a medium and it fits like a regular button down medium shirt would fit. Just enough length to tuck in the front. The sleeves are VERY short on my long arms. The bottom of the cuff hits just below the bend of my elbow. So if I roll them once the sleeves hit right above my elbows. I like the color and the feel so I am keeping it to wear front tucked with jeans.
