Alongside Princess Charlotte, other bridesmaids included Mia Tindall - daughter of Zara and Mike Tindall - Mia's cousins Savannah and Isla, Eugenie's goddaughter Maud Windsor and Robbie Williams' daughter, Theodora.

And joining Prince George as pageboy was Louis de Givenchy, who is the son of friends.

The couple's marriage was watched by around 1,200 members of the public, who were selected by ballot to listen to a live broadcast in the castle grounds, whilst thousands more lined the streets of Windsor to watch the procession outside.
