A deep and varied art dedicated to dark life of gothic subculture, gothic fashion, gothic music, gothic attitude, gothic poems,and gothic beliefs.
There are alot of things that you can like that aren't gothic but most goths like Industrial Music and Comic books. Then there are things that are definetly gothic that some goths don't care for like vampires or a fascination with death.Sometimes people may think something is really gothic when it isn't like a Alice Cooper or Rob Zombie. Like most sub-cultures, there is really no big rule that says this is gothic or that isn't gothic. Labels can be pretty slippery business.
So what you're getting here is one person's view of what is gothic art or a gothic design. I try to listen to what people are looking for in gothic designs but in the end it's my own personal experience of what has gothic meaning in my own life.
