Why do preteens cross-dress?

Well, im a preteen (young preteen) and I dont cross-dress but I know ones that do. But after a while, now I understand. When your a preteen you usually start to get hormones and you want a boy/girl to like you. So, they just want to look sexy or make themselves look hot or make people jelous. Its hard to explain. They think their almost adults and just can do whatever. They also are old enough and see actual teens cross dress and start to like their style. Apaprently, they think its swag, but other people think its wrong.
