Uniform adornment (7)
I believe the answer is:
epaulet
'uniform adornment' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for epaulet that I've seen before include "Uniform shoulder-piece" , "symbol of American rank" , "Ornamental pad on the shoulder" , "Shoulder ornament" , "military decoration" .)
