Rage about clothing (4)
I believe the answer is:
gear
'clothing' is the definition.
(gear can informally mean clothing)
'rage about' is the wordplay.
'about' indicates an anagram.
'rage' is an anagram of 'GEAR'.
(Other definitions for gear that I've seen before include "Clothing - tackle" , "Equipment - changed in the car?" , "working order" , "illegal drugs" , "Informal clothes seen in rage" .)
