The wedding of the year will take place at St Marks' Church with the reception following back at the Middleton's family home in Bucklebury, seven miles away.
Whilst the guest list has not been confirmed, Pippa's nephew Prince George, who turns four next July, is tipped to be a pageboy and Princess Charlotte, who will just have celebrated her second birthday, a flower girl.
Prince Harry will also be expected to be in attendance and there are reports that Spencer Matthews, who made his name on reality show Made in Chelsea, will be the best man.
Pippa's father Michael Middleton will walk her down the aisle, which will be decked out with colourful spring flowers likes daffodils and tulips, but no doubt it will be a less daunting task than when he also walked Kate up the aisle at Westminster Abbey.
While the designer behind Pippa's dress has yet to be confirmed, speculation arose that it might be Giles Deacon after the designer was spotted leaving her west London home with a big garment bag.
