red-carpet event (8)
I believe the answer is:
premiere
'red-carpet event' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for premiere that I've seen before include "significant performance" , "Mere pier (anag.)" , "Opening performance" , "First showing of play or film" , "First public performance of a play or movie" .)
