It really comes down to your own values and views. If you want to give an old article of clothing a continued life and feel good doing so, then do so. On the other hand, if it would bother you to (likely) have to constantly explain to people that your fur is, in fact, a vintage piece, then maybe opt for another sustainable outerwear option, such as a non-animal-fur coat made of recycled materials or vintage wool. If you can’t resell Grandma’s mink with a good conscience, arguing that whoever wears it next will be perpetuating the problem, know that there are plenty of other options than simply keeping it packed away in the deepest depths of your closet. For example, Press points out that there are organizations that repurpose old furs as bedding for rescued wildlife, which is a great (and TBH, much cuter) option.
