What fur is used on ceremonial or official robes?

Ceremonial or official robes often feature fur from animals such as minks, sable, or ermine. Ermine fur, in particular, is traditionally associated with royalty and high-ranking officials, characterized by its distinctive white color with black-tipped tails. These furs symbolize prestige and authority, commonly seen in royal robes and academic regalia. The use of such luxurious materials adds to the formal and ceremonial significance of the garments.
