Look inside, so to speak (5)

I believe the answer is:

decor

(Other definitions for decor that I've seen before include "Embellishment of a room" , "furnishings required" , "Colour-scheme etc of a room" , "Style of furnishing etc used in room" , "Furnishings and colours of a room" .)

I've seen this clue in The Wall Street Journal.
