Miner wore eastern fur (6)
I believe the answer is:
ermine
'fur' is the definition.
(I know that ermine is a type of fur)
'miner wore eastern' is the wordplay.
'wore' indicates anagramming the letters (I've seen 'worn' mean this (worn can mean damaged)).
'eastern' becomes 'e'.
'miner' is an anagram of 'ermin'.
'ermin'+'e'='ERMINE'
(Other definitions for ermine that I've seen before include "White fur associated with judges" , "special trimmings" , "'Trimming on royal robes, say (6)'" , "White fur from kind of 25 Across - judges may wear it" , "Animal with brown fur that turns white in winter" .)
