Teen Gothic

I want to understand the subculture and what it means to be goth I know I have to listen to the music but I remember seeing somewhere there's an ideology to it aswell? I also might want to try and start dressing goth not sure I know that's not needed to be goth but it's for funsies, I love the whole "alt" (in quotation marks cuz not sure if I'll get attacked for it or not) fashion from emo to punk etc I would also like music suggestions but I could also just scroll through the subreddit
