Search me roughly for fine material (8)
I believe the answer is:
cashmere
'fine material' is the definition.
(I've seen this before)
'search me roughly' is the wordplay.
'roughly' indicates an anagram.
'search'+'me'='searchme'
'searchme' anagrammed gives 'CASHMERE'.
'for' is the link.
(Other definitions for cashmere that I've seen before include "Soft fabric made from goats' hair" , "Soft wool - search me (anag)" , "Expensive wool? Search me" , "Product of fleecing operation" , "A schemer in expensive wool" .)
