I don't know, it could be a Goth wedding.
An old friend of mine had a Goth wedding, black and purple dress covered in lace with a black veil and her husband in frock coat, top hat and with a cane. They rode to the ceremony in a carriage drawn by four black horses.
And a dragon 'theme' might be very cool (
dressing as a dragon might not be, though), especially if you were Welsh or married on St George's Day.
