Instead of wearing it under the coat, I made a "coat with a fur vest" that is worn over the coat. Actually, at the end of last year, I saw a fashionable woman at the station who was dressed like that, and that's what got me started. The coat is made of beige cotton nylon fabric that is woven with high density, and it is finished just right to be worn alone in the beginning of winter and early spring. The fur vest is very convenient because you can wear it over your coat when you go outside, and then you can take it off and put it back on when you go inside a store.
