Karate belt (3)
I believe the answer is:
obi
'karate belt' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for obi that I've seen before include "Garment" , "Broad Japanese sash" , "Sash worn on Japanese kimono" , "West Indian witchcraft" , "Kimono sash; W. African sorcery" .)
