Hello, what size do you recommend for a height of 1.70 kg and 74 kilos? In addition, in one of the answers to two separate questions, it was said that the fur collar would come off, and in another answer, it was said that it would not come off. Is it possible to remove the fur collar? Can it be put on and taken off with a zipper or button? And does it have this fur inner lining? I have a question: If this leather is worn in rainy and snowy weather, will there be stains or deterioration on the leather?
