I'm 5'11" tall 135lbs, slender, small chest, long torso. I ordered black, small (which fit).  When comparing long coats the Columbia waist tends to be a bit high on me - this one was in the correct spot.  It was very flattering - hit just above the knee.  Unfortunately the arms look a bit like Michelin man and down kept coming out (sometimes poking me through my shirt).  I like how the Columbia coats have that extra material around the wrist (the half mitten thing?) - it really adds to the warmth.  This jacket does NOT have that or any way of cinching the cuffs.  Overall this coat is mid-weight for warmth.  Not a tundra jacket, not super light (like the Might Lite jackets).  I'm planning on returning this due to the down issue.
