When Beatrice was seven and Eugenie five they attended a pantomime production of Cinderella In Aid Of Children in Crisis, of which the Duchess is patron. For the special occasion The pair looked so adorable, both wearing festive tartan skirts and velvet jackets.

The York sisters were mini ballerinas back in 1998 when they attended A Christmas Extravaganza at the Theatre Royal In Drury Lane, in aid of the children's charity.

Aged 11 and nine, Beatrice and Eugenie were the picture of Christmas when they once again headed out on their annual Christmas walkabout at Sandringham.
