Fit check/advice

I recently found this old leather/lambskin coat in the attic that used to belong to my grandpa. Now, I have some wool coats but those are much more modern cut so I would love to get some advice on a couple things: 1. Do you think the coat fits well? 2. What can one wear with this kind of coat? I mean it does look a bit more elevated than what you might usually see on the street but I feel like at least any combination of jeans/sweaters would work. Any ideas and inspo are welcome though🙏 3. What kind of scarf would go well with this? If it gets real cold then I would need to cover up the open space ofc 4. Not technically related to the coat but I was wondering if you guys would let the pants cover the boots or not? Thanks in advance for any advice😌
