If you want to go big on your wedding day, go royal. And if you're going to go royal, there's no bigger inspiration than Diana, Princess of Wales. That was Mariah Carey's attitude when she married music mogul Tommy Mottola in 1993. She didn't ape Diana's entire wedding wardrobe, but she got the most recognizable part of the princess' attire down: the train.
Just how bling was this train? It was 27 feet long (which is 2 feet longer than Diana's) and required six attendants to carry it. Of course, a super-flashy train is nothing without a similarly-themed dress, and Carey's gown was not exactly low-key. She wore an extremely low-cut, billowing Vera Wang gown that was, well, fit for a princess.
