Halloween // trying to figure out couples costume, want it to be scary-ish, but niche and indie if that makes sense... pls help

I think the best way to describe what im looking for is like not too too niche where nobody understands but maybe something dark that makes sense, like old horror movie characters. striving for something gory but still cool looking. nothings popping up in my head LOL. I was Patrick Bateman last year and I thought it had a nice edgy touch to it, want something almost like that for my boyfriend and I.
