What would you wear on clash day?

the clash day at my school is in a few weeks, I'm still deciding what i wanna wear. I'm thinking getting my friends vans and switching them out so i wear one of mine and one of hers, and same with her, pigtails or one sided ponytail, a tie,a t shirt, with a completely mismatching color undershirt and tie the t-shirt up to show half of the undershirt, some leggings and short shorts over it. yeah, it sounds crazy, but hey its clash day :)
