This works with right garment (5)
I believe the answer is:
shirt
'garment' is the definition.
(I know this)
'this works with right' is the wordplay.
'works with' indicates an anagram (work can mean to twist or convulse).
'right' becomes 'r' (common abbreviation).
'this' mixed up with 'r' can make 'SHIRT'.
(Other definitions for shirt that I've seen before include "One may lose it at the bookie's" , "Garment for upper male body, usually cotton" , "Male garment worn with tie" , "Man's garment" , "tailored garment" .)
