While the princess and her younger sister, Princess Eugenie, are non-working royals with professional careers of their own, Beatrice does serve an important position within the royal family.

Much like Kate Middleton channeled Princess Diana in aquamarine Catherine Walker at Trooping the Colour on June 14, Princess Beatrice mirrored her late aunt at day one of Royal Ascot on June 17.

Princess Beatrice and Princess Eugenie are said to be "waiting in the wings" for Prince William to make a major move when he becomes King, according to a royal expert.
