Technocrat's ragged piece of clothing (6,4)
I believe the answer is:
trench coat
'piece of clothing' is the definition.
(item of clothing)
'technocrat's ragged' is the wordplay.
'ragged' is an anagram indicator.
'technocrat' anagrammed gives 'TRENCH-COAT'.
(Other definitions for trench coat that I've seen before include "Military overgarment" , "Military-style garment" , "waterproof garment" , "Military rainwear" , "item of clothing" .)
