Eh, write them however makes sense to you. There isn't, like, a goth Bible. Goth culture varies by region, by age, by everything. Sometimes they're all super dark and depressing. Sometimes they're cheerleaders with black makeup. Sometimes they're massive John Denver fans. You write them the way that makes sense to you.
People are people. They have legs, they have arms. They live in apartments, and they live on farms.
