Pippa Middleton knows how to have fun with fashion.
For the Vanity Fair and Serpentine Sackler Gallery VIP dinner in London on Tuesday, Pippa sported a flirty dress with a feathery gradient of blue and peach quite reminiscent of the 1920s.
Kate Middleton's younger sister completed the look with blue pumps and a beige clutch -- and of course, her signature year-round tan.
The Matthew Williamson flapper-esque frock was a festive choice for the swanky soirée, in which the 30-year-old writer rubbed elbows with lacrème of British society, including Vanity Fair editor Jemima Khan, advertising magnate Lord Maurice Saatchi and London mayor Boris Johnson.
Pippa was flying solo for the dinner, attending without her boyfriend of several months Nico Jackson. The couple were last spotted enjoying a date at the Boxing Ball over the weekend.
Count this as yet another fashion win for the style-savvy socialite: Only a couple of weeks ago, she was spotted at a high-society wedding with Prince William and Prince Harry sporting a gorgeous teal, knee-length dress with lace overlay.
