Okay, so I know it's a bit early for Halloween but my cousin has been bugging me asking me to help her with costume ideas, so I promised her a list of at least 15 unique costumes by the end of September that can be cheaply made, so I'm asking here for some ideas :) so here some basic information on what she's looking for.

Shes a 12 year old girl
She want unique
She wants to be able to make them cheaply with items around the house
She cant sew
She lives in Alaska so it'll be chilly (meaning there will be no zombie swimsuit models)
She's going with a group of friends so she doesn't want to be embarrassed like last year (she says she went as a werewolf and that everyone though she was a boy)
No gore, shes wearing it to school too!
