The mystery was revealed at the Royal Wedding (Fri., 6AM ET on CNN) as Kate Middleton stepped out of her Bentley and presented her much-anticipated wedding dress to the world. The newly titled Duchess of Cambridge -- Prince William is the Duke, of course -- went with modern designer Sarah Burton, creative director of Alexander McQueen.

Her head was adorned with the halo tiara Queen Elizabeth II's father, King George VI, gave her on her 18th birthday. The elegant dress was both simple and decadent, featuring a much shorter 8-foot train than the one that almost bogged down Princess Diana's arrival the last time the world stopped for a Royal Wedding.

Diana's train was a mind-blowing 25 feet long, which looked fabulous cascading behind her, but was almost overwhelming as she exited her own vehicle. Middleton's exit was flawless.

In full pomp and ceremony, Middleton made her way into Westminster Abbey and her waiting husband-to-be. As things prepared to get under way, William and Kate shared a few fleeting words and more than a few smiles. The whole world may have been watching them, but they only had eyes for each other.
