Princess Beatrice and Princess Eugenie are steadily becoming invaluable members of the royal family

Rarely courting the cameras, demanding praise or expecting fanfare, Princess Beatrice and her younger sister, Princess Eugenie, have taken on something of a higher profile within the royal family in recent months – with some predicting that they will soon prove to be some of The Firm’s most underrated star players.

‘Although Prince William still believes in a “slimmed-down monarchy”, he is increasingly aware of the hard work of his extended family,’ one courtier told MailOnline. The sisters do appear to be much valued by their cousin, who has now issued them both with invitations to garden parties at Buckingham Palace on consecutive years – with Princess Beatrice only missing the most recent event to attend the Matrix Awards in New York for women in communications.

At the most recent garden party, hosted by Prince William and the Princess of Wales, Princess Eugenie was present and correct, wearing a classic navy-and-white polka-dot gown that echoed the style worn by Kate several weeks previously. She teamed it with a smart, navy boater and a stunning pair of sapphire-and-diamond earrings by royal jeweller, Garrard, looking every inch the modern Princess as she chatted to guests and mingled on the lawn with her cousin.
