Kate Middleton is having her first Royal Christmas at Sandringham Estate, but this will require changing into five different outfits, according to ABC News' royal correspondent.

The Duchess of Cambridge will be among 27 guests at the 20,000 acre Royal Estate. Middleton told the media she was looking forward to the Royal Christmas event, and confirmed that she would need to change outfits about five times throughout her stay, according to The Sun Newspaper.

Kate will need a casual outfit for breakfast, a smart outfit and a hat for the morning church service, a dress for lunch, a cocktail dress for early evening drinks and a full-length dress for the evening meal, ABC News' royal correspondent Kate Nicholl told GMA.

Since marrying Prince William in a Sarah Burton for Alexander McQueen dress, Middleton has been revered as one of the biggest fashion icons of the year.

The world has become so accustomed to the Duchess' chic and elegant style, that she baffled thousands of people when she showed up to an informal meeting at a primary school in jeans.

The children were shocked saying, She doesn't look like a princess. In past visits to charity organizations the duchess' outfits had been covered by the media as much, if not more, than the visits themselves. Her wardrobe has been followed so closely that in November Middleton topped British Harper's Bazaar's best-dressed list.

There have been no leaks as to what the Duchess will be wearing at Sandringham, but Royal enthusiasts anticipate that months of planning have gone into her attire for the special events

The festivities at Sandringham will kick-off on Christmas Eve with the elaborate decorating of the Sandringham coniferous tree, according to All Voices. Trestle tables will be placed underneath the tree where royals will have tea and snacks and place their presents under the tree.

At midnight the Queen will attend the communion estate church with her royal guests. On Christmas day the royals start with a grand breakfast, followed by a church service and grand Christmas lunch at the King's Dining Room.
