Doris cavorting by couch, undressed (8)

I believe the answer is:

disrobed

'undressed' is the definition.
('disrobe' can be a synonym of 'undress')

'doris cavorting by couch' is the wordplay.
'cavorting' indicates anagramming the letters.
'by' says to put letters next to each other.
'couch' becomes 'bed' (I've seen this before).
'doris' with letters rearranged gives 'disro'.
'disro'+'bed'='DISROBED'

(Another definition for disrobed that I've seen is " Undressed".)

I've seen this clue in The Telegraph.
