Who wore it best?

It seems Pippa Middleton‘s been taking style tips from saucy Kelly Brook.

Kate Middleton‘s little sister slipped into the same dress worn by the raunchy model for a society wedding in Northumberland this weekend.

Despite their different body shapes, the monochrome peplum number flattered both girls’ figures.

It added curves to Pippa‘s sporty frame and enhanced Kelly‘s womanly shape.

Recently photographed topless while on holiday in Mexico, 33-year-old Kelly stepped out in the frock in May, glamming it up with tumbling waves and peeptoe platforms.

Pippa opted for a more sophisticated look to attend the marriage of Lady Melissa Percy and Thomas van Straubenzee with Prince William and Prince Harry.

She finished off her outfit with an up-do, court shoes and a dramatic hat.
