Faux Leather & Faux Fur Belted Coat

Not sure if this jacket fits. It is extremely narrow in the waist so I don't see how I'm going to be able to wear a blouse under it. The closure button is a hook which makes the jacket feel like a costume with the deep v neck style completely open in the front. Then from the side view the jacket has all this extra flowy fabric with fur trim making my butt look big. Is that supposed to be flattering? I wonder what size the fit model was. The texture and design looks and feels luxe but it just doesn't feel practical as outwear for the Fall / Winter months.
