Elizabeth Emanuel, who designed Princess Diana's dress thirty years ago, chats with Piers about what she predicts the new princess's dress will look like. Emanuel is confident Kate's dress will look nothing like Diana's. She describes Kate's look as "very classic, quite plain actually." She does think we'll see something unexpected. "I'm sure there is going to be some kind of a twist." Emanuel explains since we don't know who the designer is we can't speculate on the style.
