Lots of eyeliner (on the eyeline and under) wear light pink lipstick bleach your hair (or wig) and straighten hair flat and get a neon green streak in it. Wear crazy girly rebilious outfits like a collage with lots of colors!
You can dress as Avril Lavigne for Halloween by wearing light or dark color lipstick bleach. You can also put on a hair wig or blond hair extension and then straighten hair flat. Just put on something crazy for the event.
