I first got a Small and it fit just right, but when I raised my hands or stretch them in front of me, the shoulders felt a little tight, so I changed for a MEDIUM and it fits nice.loose with room to layer, and I like my jackets and coats a little loose anyways.it helps that you can synch in the waist line.for reference I am about 5'7"120 lbs., shoulders about 15.5", bust 35", waist 30" hips 39"the sleeve length fits down mid palm, when my hands are down, and the coat length lays about one hand length above my knee.great deep pockets, NOT water resistant, but dries fast, if you got sprinkled on.happy with the purchase.
