Pippa Middleton really dressed the part as she sailed down the River Thames in a nautical-inspired ensemble for the 1000-strong Diamond Jubilee boat pageant.
The Duchess of Cambridge's sister donned a navy jacket with a cream trim, along with a matching pleated skirt, by Milly.
Pippa was joined on the Elizabethan by her father, Michael, and brother, James, as well as her mother, Carole, who was as smart as ever in a cream skirt suit.
The Elizabethan was part of the Royal Squadron - a number of boats that sailed behind the Queen's - and the family were all smiles as they waved at the crowds and the cameras.
Although Pippa looked stylish, on this occasion, her outfit wasn't quite a match for sister Kate's striking scarlet Alexander McQueen number.
From street parties to the Thames pageant, and from Katherine Jenkins to Kate Middleton, see ALL the photos from the Diamond Jubilee weekend so far:
