Wan't to go in the scene direction? Help needed.?

Okay. So I am a 14 yr old girl who will be going into High School next year. I honestly hate the way I dress (My clothes are so boring and I have no distinct style). I wan't to be able to wear the clothes I wan't (And in my mind I have a very set look) but I don't think my parents will be very happy. Let's just say they are a little bit like a mine. They are set off by even the smallest disturbance. And honestly, right now I can't afford to get on their bad side (For reasons I won't even approach). I am very into alternative/rock/punk music and although my parents are semi aware of my taste (And are very unhappy as it stands) they have no idea about how serious and obsessed I am with it and how important my music is. My music kind of reflects my style and that's where my problem begins (Sorry btw by describing my style as scene, I hate labels but it's the closest thing I could think of) Anyway, I'm not crazy enough to suddenly jump into the boat and scare the **** out of my parents, I just wan't to know how to handle my situation without pissing them off. Honestly, I don't mean to sound like a poser or whatever but it is CRUCIAL I don't get them mad. That's the only reason I haven't just talked to my parents or bought clothes of my taste.
