Style of furnishings (5)
I believe the answer is:
decor
'style of furnishings' 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" , "ornament" , "Internal ornamentation" , "Furnishings and colours of a room" , "Interior colour scheme and furnishing" .)
