Innovative act ruined with drapes (9)

I believe the answer is:

curtained

'with drapes' is the definition.
(having curtains or drapes)

'innovative act ruined' is the wordplay.
'innovative' indicates an anagram.
'act'+'ruined'='actruined'
'actruined' anagrammed gives 'CURTAINED'.

(Other definitions for curtained that I've seen before include "Out of public view" , "concealed" .)

I've seen this clue in The Guardian.
