State old raiment is worn out — by these folk? (15)
I believe the answer is:
tatterdemalions
'out by these folk?' is the definition.
The definition suggests an adverb but the answer is not.
'state old raiment is worn' is the wordplay.
'is worn' indicates an anagram (worn can mean damaged).
'state'+'old'+'raiment'='stateoldraiment'
'stateoldraiment' with letters rearranged gives 'TATTERDEMALIONS'.
(Other definitions for tatterdemalions that I've seen before include "Tramps" , "Scruffy kids" .)
