You don't wear it often. It is no problem to do maintenance once every 2-3 years, but the time should not be too long. On the one hand, some dust will stick when you wear it, on the other hand, with the passage of time, the oil in leather will be lost, so the leather will gradually lose its luster and even become hard. I don't know what color your fur coat is and what technology was used when it was made, so I can't tell you how to maintain it in detail. I suggest you go to a professional leather care shop for maintenance, and try not to go to dry cleaners, because most dry cleaners are not professional enough and will treat all leather clothes equally, so the things they make are uneven. There are many professional nursing shops here. Lv Yun Leather Care Store in Yanling Lane, Xinjiekou, I know it very well, 84409329. Maybe you can consult and try.
