Clothes advice and help?

I'm in high school and I dress very professional. I wear pencil skirts, blazers, pantyhose and heels. I like this look, but I also like punk and goth. So how can I come off as more punk while still dressing this way? I go to shows, but people don't want to have anything to do with me because of the way I dress. If I say I like punk or goth people are surprised because I don't "look" like the type of person that would like it.
