Adornment (10)
I believe the answer is:
decoration
'adornment' is the definition.
(I know that decoration is a type of adornment)
This is all the clue.
(Other definitions for decoration that I've seen before include "Adornment - medal" , "New Year's honour, say" , "Medal; ornament" , "Bunting (in honour of a brave man?)" , "Flags put out" .)
