Interior look (5)
I believe the answer is:
decor
'interior look' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for decor that I've seen before include "Interior layout and furnishings" , "Scheme of interior furnishings" , "Style of furnishings, drapes etc used in a room" , "Internal ornamentation" , "(Room) design" .)
