Middleton and Matthews have been engaged since July 2016 when Matthews proposed during a trip to the Lake District. 

Pippa, 33, wore a gown by British designer Giles Deacon, who said he was "thrilled" to work with her on her wedding dress.

The Duchess wore a peach Alexander McQueen dress and matching hat as she was seen helping the children in the bridal party go into the church.

The bride’s 3-year-old nephew, Prince George, served as a pageboy. His sister, Princess Charlotte, 2, was a bridesmaid.

The Duchess of Cambridge admitted last week that she was a little worried about how her children would act at the affair, but was “hopeful they would be good.”

Middleton's reception will take place at her parent's home in the English countryside, where a giant glass enclosure has been constructed for the 300 guests expected to attend the reception.
