Frippery (7)
I believe the answer is:
regalia
'frippery' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for regalia that I've seen before include "Badges of office" , "Orb and sceptre etc" , "Crown, sceptre etc used at a coronation" , "ceremonial gear" , "Trappings of royalty" .)
