I ordered a small size. I'm 5'8 and 150 lbs. My size in coats sometimes gets a little complicated. I wear small when it comes to jackets and medium when it comes to shirt. This coat is nice and warm. And I like the style too. But I wish it was a little more trim-fit or snug on the waistline. And that the bib is removable. Now I'm not sure if I should just return it and spend $200 more at the mall. Otherwise, it's a nice warm and cool design coat. This would be perfect if you're on a beefy side even if you're short.
