Ceremonial wear used in afro-beat (4)
I believe the answer is:
robe
'ceremonial wear' is the definition.
(I've seen this in another clue)
'in afro-beat' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ROBE' is hidden within 'afro beat'.
'used' acts as a link.
(Other definitions for robe that I've seen before include "Dressed buffalo hide" , "Gown, rich dress" , "judge's garment" , "Formal vestment" , "Loose garment for Boer" .)
