What should Twilight Sparkle’s Canterlot friends dress up for Nightmare Night?

I can see MoonDancer not choosing to wear a costume, and story being her friends trying to get her to dress up and enjoy Nightmar Night.

In an episode Minuette actually dress up like a surgical doctor.

Maybe Lyra dress up as Nightmare moon, mostly as a joke/ trying to steal as much candy from children.

Twilight going for her gavorite Starswirl... or loosing a bet and choosing instead to go as smol princess Celestia.

Lemon Hearts going for the pirate theme.

Twinkleshine would definitly go as "famous" celebrity of theaters.

Lyra as a knight, not royal guard.

Minuette will go as a dentist, as a joke.

And how would the bet go? Also I think Twilight Sparkle dressing up as Princess Celestia informs Nightmare Night is a good costume for her to dress up as someone who looks up to their mentor and ruler.

Pretty much it was an idea as it is... because Twilight would be Starswirl no matter the universe.

Probably have Lyra make a bet with all the others in the Running of the Leaves on who would win and the Canter 6 would end up dressingvas Pretty Soldiers Sailor Moon.
