Please spell everything right, OP. A few seconds of Googling would suffice.
I'm European, and in certain circles, we have debutante balls too. They originated to introduce young noble ladies of marriageable age to their Majesties, the court, and to eligible bachelors. Their families hoped to marry them off before their 20s.
So it's ball gown. Débutante (French, feminine, means "beginner", as in, starting out in the world).
You could rent a hotel ballroom, invite all her friends, tell them the theme is formal ball gown, and have a huge party, limos, photoshoot, mocktails, fancy food, etc. You could attach a specific historical period to it, or not. You could go SteamPunk Goth Victorian, or Elven, or whatever. Or just the Cinderella vibe she seems to want.
She's old enough to be aware of the costs of the event, and compare them to her future college expenses, car, etc. It all comes from the same pot, and you need to sensitize her to budgeting.
So she can have whatever party she wants, within your wallet's limitations. Débutante balls are a caucasian tradition from Europe, exported wherever Europeans migrated to. (The Spaniard Quinceanera is an off-shoot of that. Just don't call it that.)
