Japanese garment (6)
I believe the answer is:
kimono
'japanese garment' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for kimono that I've seen before include "Japanese style of robe or gown" , "Japanese attireimoni" , "Oriental gown" , "Japanese clobber" , "Woman's loose robe, tied with a sash" .)
