Bit of floor decor (3)
I believe the answer is:
rug
'bit of floor decor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rug that I've seen before include "Thick-piled floor mat" , "Mat or knee-cover" , "Wig (informal)" , "Informal term for a toupee" , "Hairpiece" .)
