However, I would very much like him to don a tie for his ultimate finale, please. He needs his tie.

He's been seen in three different costumes for the finales, from what I can tell. The Midnight-ish one from this clip, and then other times the light blue shirt with (a) the brown tie with blue triangles (I think), and (b) a new variant of the swirly-whirly tie.
