I want to become a goth how I can ??

I am goth too, so I can help. For gothic makeup, try black lipstick, black eyeliner, and the darkest eyeshadow you can find. If you are not allowed to have black lipstick, try dark purple, with black lip liner. For hair, you don't have to do anything. If you really want to, but are not allowed to dye your hair, try grtting red and black highlights. For clothes, you can wear anything black.
