Search me after messing up fine material (8)
I believe the answer is:
cashmere
'fine material' is the definition.
(I've seen this before)
'search me after messing up' is the wordplay.
'after' is a charade indicator (letters next to each other).
'messing up' is an anagram indicator (I've seen 'messed up' mean this).
'search'+'me'='searchme'
'searchme' is an anagram of 'CASHMERE'.
(Other definitions for cashmere that I've seen before include "Expensive wool? Search me" , "Soft woollen fabric" , "Fine goats' wool from Kashmir" , "Soft wool of a type of goat" , "See charm (anag)" .)
