Princess Diana's wedding gown travels in style!

Princess Diana's wedding dress has travelled to the Mall of America in Bloomington to be the star of a royal exhibition opening this Saturday, 'Diana: A Celebration.'

Graeme Murton and Nick Grossmark are the only two people in the world who are permitted to handle the iconic wedding gown. As a result, they have travelled with the gown worldwide, this being their 14th stop on the exhibition's tour.

The dress travels in a foam-lined crate, large enough to hold the dress hanging on a manequin. It is wrapped in tissue, and is only ever handled by Graeme and Nick wearing white gloves.

It's been 30 years since the royal wedding in July 1981, but it still remains one of the worlds most iconic weddings.

The train of the dress is the longest in royal history, measuring 25 feet long. Usually on display at the Althorp Estate, the dress has generated millions in charity contributions, with over 1 million people having visited the exhibition.

The exhibition holds 150 objects including 28 dresses, momentoes and rare home movies.

It was only last year that Buckingham Palace held a royal exhibition on William and Kate's wedding, which was also hugely popular.
