Pippa Middleton Rocks Feathered Dress Without Kate Middleton (PHOTOS)

Kate Middleton, eat your heart out!

The Duchess of Cambridge's younger sis, Pippa Middleton, showed off her cheeky sense of style when she sported a 1920's-inspired drop-waist dress with a two-toned feathered skirt at the Vanity Fair and Serpentine Sackler Gallery VIP dinner in London on Tuesday.

With her trademark wavy locks and Alps-worthy tan, Middleton looked better than ever and seemed to relish the attention even if her royal sister and nephew Prince George weren't there to share in the celebrations.

Also MIA at the party was Pip's boyfriend, Nico Jackson, who has been dating the party girl-about-town for almost a year.

But the Vanity Fair correspondent got to mingle with another kind of royalty -- that of the socialite. Princess Diana's former friend Jemima Khan (who shared some tidbits about the late Princess of Wales to Vanity Fair in a recent issue) was photographed chatting with the 30-year-old author. Bet they have a lot to talk about!

We can't get enough of Pippa:
