Fashion an item for prisoner (6)
I believe the answer is:
inmate
'for prisoner' is the definition.
(inmate can mean someone in prison)
'fashion an item' is the wordplay.
'fashion' is an anagram indicator.
'an'+'item'='anitem'
'anitem' with letters rearranged gives 'INMATE'.
(Other definitions for inmate that I've seen before include "eg Prisoner" , "Inhabitant of prison or other institution" , "One is confined to an institution" , "Convict" , "Inhabitant of prison or hospital" .)
