So for my school we are having a contest/party, and the best dressed will receive an A, and a week of no homework. The students will vote. The catch is, it has to be mainly made with things at home, yes we can use clothes. But things like yarn, or spray paint, etcetera.

My question is,
what might be a good halloween costume, that can be homemade, but still likeable.
Me and my friends were thinking about a mocking Miley Cyrus ensemble for me, since I am plus-size. The teacher says it is acceptable, but are there any ideas out there that might work better?
