Im a 16 year old girl, and I honestly hate the costume choices for girls my age. The ones at the dances have no creativity whatsoever, they barely even qualify for costumes.
I have always gone as my favourite movie characters. the last 3 years of highschool have been guys. Grade 9 I was Jack Sparrow, Grade 10 I was ghost rider( homemade) and grade 11(this year), i saved my money and I bought a grand heritage 200$ costume. Halloween is my favourite holiday and I actually try to put some effort into it.
ETA: This is my ghost rider costume from last year.
