How can I dress more feminine but still stay in my comfort zone?

Wear more jewelry! I wanted to do the same thing, and what you do is just simply wear more v necks. Like the one that was on that website!!! You should wear that with skinny jeans or leggings, and if you aren't ready for that... then just wear it with capri's or pants. If you get like three tops and wear them, people will really notice your change already. Just look for what will bring it out a little bit at a time.
