Pose dressed for not much money (4)
I believe the answer is:
peso
'not much money' is the definition.
(monetary unit in some countries)
'pose dressed' is the wordplay.
'dressed' is an anagram indicator ('dress' can mean 'prepare').
'pose' anagrammed gives 'PESO'.
'for' acts as a link.
(Other definitions for peso that I've seen before include "Piece of eight" , "Latin American money" , "Chilean currency" , "Foreign currency" , "Mexican currency unit" .)
