How do I be more feminine?

I think I act like a boy way too much and I wanna be more girly but in like a mature way. I don't wanna be like all weird and overly girly; just have more womanly appeal with the way I talk and move and what not. Lately I've noticed that the things I talk about are like what my brothers would say and it not very lady like lol. I mean I look like a girl haha but I'm not as girlish as I used to be with getting ready in the mornings. I get up and straighten my hair almost everyday and I wear a little bit of makeup whenever I'm going out in public like school and stuff, but I don't bother getting very dressed up or anything mostly cuz I don't have a lot of cute clothes (or a lot of money to buy clothes) and when I do go shopping I'll usually just get a t-shirt or something cuz I don't know how to pick out outfits. And I subscribe to magazines like glamour, vogue, marie claire, and allure and I read those when I have time. So i dunno I'm just having problems talking like a lady and being graceful and stuff which is how I want to be. How do I change the way I act so I'm more lady like and womanly?
