Fold in garment cut for suit (4)
I believe the answer is:
plea
'suit' is the definition.
(thesaurus)
'fold in garment cut' is the wordplay.
'fold in garment' becomes 'pleat' (I've seen this before).
'cut' means to remove the last letter.
'pleat' with its last letter removed is 'PLEA'.
'for' is the link.
(Other definitions for plea that I've seen before include "Excuse, entreaty" , "Formal statement of guilty or not guilty" , "Defendant's answer to a charge or claim" , "Heartfelt request" , "Urgent request" .)
