Underwear for barristers (6)
I believe the answer is:
briefs
This clue is a double definition.
'underwear' is the first definition.
(I know that Briefs is a type of pants)
'barristers' is the second definition.
(informal term for a lawyer or barrister)
'for' is the link.
(Other definitions for briefs that I've seen before include "Documents stating facts and points of law" , "small underwear" , "Digests" , "by which privates will be constrained" , "Underpants, knickers" .)
