Compensation concerning clothing (7)
I believe the answer is:
redress
'compensation' is the definition.
(I know that redress is a type of compensation)
'concerning clothing' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'clothing' becomes 'dress' (dress is a kind of clothing).
're'+'dress'='REDRESS'
(Other definitions for redress that I've seen before include "Set right - compensation" , "Reparation" , "remedy" , "Correct" , "set things right" .)
