I believe there are no people left on the planet who, at least in general terms, do not know about twilight, vampire mania and all this nonsense. Therefore, it will be enough to read “Twilight” and everyone will understand the general meaning of what is happening (well, except for the 95-year-old grandmother Gretta blindly squinting at her black and white TV, but I think this is insignificant).
And of course the costume.
Yeah, but it still makes the songs they chosen a bit random. If she is portraying an innocent girl turning into a vampire, they should use a song from Breaking Dawn also, but there are using only Twilight and New Moon songs when Bella was still fully human.
Even that everyone knows in general terms what Twilight was about, it was nearly a decade ago, when it was a big thing. Nowadays from a girl her age you would expect that she would want to skate to songs from The Chilling Adventures of Sabrina or Stranger Things, but not Twilight.
But she enjoys it so it's what really matter.
