Im a myself or im a wanna/fake person?

If you truly like fashion and you don't pretend to like it then you're being yourself. As long as the clothes you wear represent who YOU are then that's not being fake at all. You don't have to have money to be into fashion, and even if you didn't like it before you like it now and people's interests change as they get older, especially when they're teenagers. So no, you're not fake.
