Pippa Middleton's Diamond Jubilee River Pageant Cruise

With her royal sister stealing the show in a bright red McQueen frock, Pippa Middleton also brought her stylish self to the Diamond Jubilee Thames River Pageant festivities in London on Sunday (June 3).

The 28-year-old brunette beauty was alongside parents Michael and Carole and brother James aboard the paddle steamer the Elizabethan as Queen Elizabeth II celebrates the 60th anniversary of her ascension to the throne.

As for her wardrobe choice, Pippa was decked out in a navy and off-white ensemble including a jacket paired with a pleated knee-length skirt.

With Kate and the royal family leading the way on the Spirit of Chartwell, the Middletons looked quite content as they sipped champagne and waved to onlookers from their sea vessel - as the Elizabethan is described as having ''the unique exterior of a 19th century Paddle Steamer coupled with the interior of a top London restaurant and night club'."
