Stole, perhaps (4)
I believe the answer is:
mink
'stole perhaps' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mink that I've seen before include "Weasel relative (or its fur)" , "Source of fur for coats" , "Slender mammal, valued for its fur" , "(Fur from) small carnivore" , "A mammal; a fur coat" .)
