Teen Gothic

I’ve been into the subculture for years now and have been listening to the music and attending shows. Now I’m going to a goth club for the first time in LA next week. I’ve never been in any type of night club. I’m going with my brother who isn’t in the goth scene but is always down for an adventure so I won’t be alone. I’m excited to finally get to experience the goth club scene(Im 23). Any advice for someone new to the club scene? Anything I should know about beforehand?
