I bought one a while ago. It's cut slim. I'm generally a size 36 but I went for 38, which is comfortable and I can just barely fit a sport coat underneath . Narrow shoulders and sleeves, high armholes. I got mine from Nitty Gritty and it came with a removable wool liner in Black Watch plaid. If you're not familiar with Mackintosh bonded cotton fabric, you'll probably find it unusual. It's very stiff and I find it wears pretty warm, so it's probably best for cooler days. It also has a distinctive smell. Completely waterproof though. I really like the coat and enjoy wearing it.
