Kingly fur (6)

I believe the answer is:

ermine

(Other definitions for ermine that I've seen before include "White-coated stoat" , "'Trimming on royal robes, say (6)'" , "White fur of stoat" , "Stoat in northern regions" , "Fur trimming on royal robes" .)

I've seen this clue in the King Feature Syndicate.
