My ideal wedding sounds more vampyric than gothic, but eh.
It would be in a gothic cathedral, with all the guests wearing black, same with the bridesmaid and best man, etc. The bride would be carried inside a closed casket to the altar by six of my most trusted friends(three on each side). As the casket reaches the altar, the 'carriers', as I would call them, would walk bback to their seats as I open the casket, then lift the bride, wearing a black wedding gown, off the casket next to me. Then I'd have the preacher go on with his yatayatayata "you may now kiss the bride" crap, kiss the bride, then carry her out of the chapel onto a black hearse that'd take us out of their and blahblahblah.
That, of course, is my simple non-detailed explanation. I didn't wanna get too into detail. It'd take forever.
