Lawyer's clothing (6)
I believe the answer is:
briefs
'lawyer's clothing' is the definition.
'briefs' can be an answer for 'clothing' (I've seen this before). I'm not sure about the 'lawyer's' bit.
'lawyer's clothing' is the wordplay.
'lawyer' becomes 'brief' (I've seen this before).
'clothing' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'brief'+'s'='BRIEFS'
Can you help me to learn more?
(Other definitions for briefs that I've seen before include "Abstracts" , "Orders" , "They are prepared for barristers' perusal" , "Close-fitting underpants" , "Garments" .)
