I don't know how old it is. But I do know that in Australia, debutant balls are often put together by high schools.
Well oddly enough  In Australia, débutante balls (or colloquially ''deb balls'') are usually organised by high schools
I've always wanted to be a debutante! I see, I know a debutante comes from an upper-class or aristocratic family. Does that apply to you? Welp, I don't have an aristocratic or upper-class family, so I guess I'm out of luck! At what age do most debutantes have their big, elaborate balls? I'm not sure, but becoming a debutante meant that you were old enough for marriage, and one purpose of the coming out was for display her to bachelors. Oh, I see! It seems like debutantes have a lot of history? Is this an old term?
In Australia, débutante balls (or colloquially ''deb balls'') are usually organised by high schools, church groups or service clubs, such as Lions or Rotary.
