Search for a soft garment (5)
I believe the answer is:
probe
'search' is the definition.
(probe is a kind of search)
'a soft garment' is the wordplay.
'a soft' becomes 'p' (musical abbreviation for 'piano').
'garment' becomes 'robe' (robe is a type of garment).
'p'+'robe'='PROBE'
'for' acts as a link.
(Other definitions for probe that I've seen before include "Question or examine closely" , "Inquiry" , "Examine searchingly" , "(Crime) investigation" , "Poke into" .)
