Clothes that fit badly after being much cut down (5)
I believe the answer is:
mufti
'clothes' is the definition.
(mufti is a kind of clothes)
'fit badly after being much cut down' is the wordplay.
'badly' is an anagram indicator.
'after' is a charade indicator (letters next to each other).
'being much cut down' becomes 'mu' (I can't justify this - if you can you should give a lot more credence to this answer).
'fit' anagrammed gives 'fti'.
'fti' put after 'mu' is 'MUFTI'.
'that' is the link.
Can you help me to learn more?
(Other definitions for mufti that I've seen before include "No official dress" , "Civilian gear" , "Civilian attire" , "Plain clothes - Muslim legal expert" , "Soldier's civilian clothes" .)
