Most Halloween weddings on the Web aren't gothic. They're of the "let's have a silly Halloween party and get married too!" variety. This actually could be a good way to sneak gothic touches into your wedding, if your family protests at more traditional goth things. Have an October wedding, call it a masquerade ball, and that allows everyone to dress in non-standard wedding attire. These sites may give you a few ideas.
