Here are a front view with the front open, a 3/4 view and a close up my son took which shows the colour and weave better.
I had a set back when I decided to interline the lining with flannel. It is very warm, but snugger than the mockup was. It doesn't help that I have gained about 20 pounds recently. I almost gave up on it, but really wanted it out of the sewing room. In the end it fits fine, even with the flannel.
