I just bought a CG chateau parka in both large and medium and am having some serious trouble getting the right fit. I like how it looks in medium; but it is slightly tight around my butt; like I actually feel it being tight, especially sitting down. Large, at first glance, is not that much larger, but it does look slightly baggy; especially in the end of the jacket, where instead of wrapping around the legs, the jacket kind of sticks out forward, if it makes sense. However, large is lose and comfortable - with no tightness at all. Could you share your experience with the jacket and how you went about finding the right fit and size. I am, by the way, 5'11 and about 150-155 lbs. Thanks.
