I wear a size 18 and ordered the 1X and the fit was good, But if you like extra room for sweaters order one size bigger. The hood does not detach. There is furn on the hood and fur on the collar and it is soft and very real like. The pockets are two ways zipper for small and top pocket clip for large which is the one I like. The coat is extremely warm and actually hot if shopping in it. The sleeves have an inner cuff which fits very snug on the wrists and does not let cold air in. The waist is adjustable for a nicer fit.
