Chin curtain or goatee (5)
I believe the answer is:
beard
'chin curtain or goatee' is the definition.
(I know that chin curtain is a type of beard)
This is all the clue.
(Other definitions for beard that I've seen before include "Whiskers" , "Facial growth" , "hair extension" , "Facial feature" , "Boldly confront (formidable opponent)" .)
