Outfit with feathers gets reprimand (5,4)
I believe the answer is:
dress down
'reprimand' is the definition.
(I know that reprimand can be written as dress down)
'outfit with feathers' is the wordplay.
'outfit' becomes 'dress' (I've seen this in other clues).
'with' is a charade indicator (letters next to each other).
'feathers' becomes 'down' (down can mean bird feathers).
'dress'+'down'='DRESS DOWN'
'gets' is the link.
(Other definitions for dress down that I've seen before include "Censure" , "lecture?" , "Severely criticise" , "Put on casual clothes" , "Rebuke" .)
