Teen Gothic

So I’ve been listening to some goth music and seeing how people dance to it and it seems like a lot of fun. While I’m not goth (I dress fairly basic) I’m very into 90s alt, hardcore, and nu-metal. When I’m dancing at a party to pop or rap I feel very trapped and insecure but goth dancing seems very free flowing and fun. I also want to meet new people and stuff. Should I go and how should I dress with the limited stuff I have?
