Clothing is torn without intention (7)
I believe the answer is:
raiment
'clothing' is the definition.
(raiment is a kind of clothing)
'torn without intention' is the wordplay.
'torn' becomes 'rent' (rending is a kind of tearing).
'without' indicates putting letters inside ('without' can be similar in meaning to 'outside').
'intention' becomes 'aim' ('aim' can be a synonym of 'intention').
'rent' going around 'aim' is 'RAIMENT'.
'is' acts as a link.
(Other definitions for raiment that I've seen before include "Garb" , "investment" , "Clothing (literary)" , "these garments are old-fashioned" , "Clobber" .)
