Judge's garb (4)
I believe the answer is:
robe
'judge's garb' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for robe that I've seen before include "habit" , "Dressing-gown" , "judge's garment" , "Long loose garment or dressing gown" , "Old cloak for Boer" .)
