Cut in tattered garment (5)
I believe the answer is:
tunic
'garment' is the definition.
(historical type of garment)
'cut in tattered' is the wordplay.
'tattered' is an anagram indicator.
'cut'+'in'='cutin'
'cutin' is an anagram of 'TUNIC'.
(Other definitions for tunic that I've seen before include "Close-fitting jacket that's part of a uniform" , "Dress for soldier" , "School garment" , "Clobber" , "Policeman may be in one" .)
