How to be a girly girl?

I've noticed I kind of give off a vibe that shows me as an aggressive girl, when really all I'd love to be is an innocent girly girl. Of course being me I am totally clueless, and I know that their are a lot of chic girly girls, so if you'd give me your tips on everything from what to wear and how to act and how to present myself, then I would be stoked. :) thanks for all your tips!
