Hair adornment (3)
I believe the answer is:
bow
'hair adornment' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bow that I've seen before include "Front part of a ship" , "Bend in obeisance" , "Make reverence" , "Weapon for shooting arrows" , "Acknowledge applause as actor does" .)
