The EB coat is a waterproof trench-like shape but without a belt so not quite so waist-defining. The quilted lining is attached with buttons around the edges and can easily be removed. I got a petite large which is just big enough to fit a fairly thick sweater even with the lining attached. It's been fabulous for winter travel to European cities (which we've done off and on for quite a few years around Christmas) because it's waterproof in case of rain but also quite warm although in Oxford England it was not quite warm enough for walking around for several hours. It has all the desirable bells and whistles - zip up pockets, removable hood, and zipper that opens top and bottom. It does make a little bit of noise when you move, like some Gore-Tex does. The sleeves were too long so I shortened them, which meant shortening both the coat AND the lining, and I did it by creating an extra pleat/seam above the elbow so as to not mess with the button and buttonhole where the lining sleeve attaches to the outer sleeve at the sleeve cuff. My arms are proportionally a bit short so you probably would not have this issue.
It would not be warm enough for outdoor walking for me in deep winter, but might be just right for your climate.
I find EB fits a little bit slim, like Jcrew, which I would think would be perfect for you, if you can find the right size.
If you click on the find it seems to go nowhere but if you go to EB's site and search for it you'll find it.
You may know this already but EB quality is top notch.
