How would I know knitted cashmere? (6,2)
I believe the answer is:
search me
'how would i know' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'knitted cashmere?' is the wordplay.
'knitted' indicates an anagram (knit can mean to screw up or crease).
'cashmere' is an anagram of 'SEARCH ME'.
Can you help me to learn more?
(Other definitions for search me that I've seen before include "Who knows? 14 [NOT-I] !" , "I don't know (colloq.)" , "I don't know, informally, about cashmere - frisk away" , "I haven't a clue" , "what customs officer might do" .)
