One reason why fur may be fetishised is perhaps that the garment forms a "second skin" that acts as a fetishistic surrogate for the wearer's own skin. This is heightened by the fact that the fur was originally an animal's skin and hair.
One of the earliest documented examples of fur fetishism was the case of the eponymic Leopold von Sacher-Masoch, both in real life, and in his semi-autobiographical novel Venus in Furs (Venus im Pelz).
