Sash for a kimono (3)
I believe the answer is:
obi
'sash for a kimono' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for obi that I've seen before include "Martial arts sash" , "Japanese band" , "belt" , "Japanese sash - African witchcraft" , "Charm used in witchcraft" .)
