Pinterest can help you. There's a ton of fashion out there.
I don't know what type of indie you're talking about between indie or indie kid. If indie kid, anything brightly colorful mix with blood and gore will work.
But if it's indie, let me be honest, indie is about being yourself, not following fashion trends or other people's fashion sense. Just be yourself, dress whatever you want, don't follow anything mainstream just because they are popular. You can also mix up some gore into it like painting some of your clothes with red paint to make it looks like blood or put on some gore inspired jewelry.
