Do like lifting uniform with character, mostly, and something decorative on it? (9)
I believe the answer is:
epaulette
'do' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
I don't understand the rest of the clue.
(Other definitions for epaulette that I've seen before include "Shoulder badge or ornament" , "Military decoration" , "Ornamental shoulder piece on clothing" , "Shoulder decoration" , "rank stars here?" .)
