Decorates, embellishes (6)
I believe the answer is:
adorns
This clue is a double definition.
'decorates' is the first definition.
('adorn' can be a synonym of 'decorate')
'embellishes' is the second definition.
(adorning is a kind of embellishing)
(Other definitions for adorns that I've seen before include "Bedecks" , "decks" , "Adds ornamentation" , "'Decorates, embellishes (6)'" , "Decorates with ornaments" .)
