Kate Middleton Wore A Sexy Halloween Costume In 2007

One thing's clear: Kate Middleton used to love sexy Halloween costumes!

A 2007 photo of the Duchess of Cambridge dressed up as a seductive witch is circulating on the Internet just in time for Halloween.

In the pic, a 25-year-old Kate sported a black sequin mini-dress over a dramatic cape, which she paired with fishnets, matching black boots and a pink purse. And of course, Kate's signature blow-out was in full swing!

The future Duchess, who had recently rekindled her relationship with Prince William, enjoyed herself while partying with younger sis Pippa at London's Mahiki Club.

Being photographed by the paparazzi was one of the ways Catherine fought to get Will back after their April 2007 split. According to Us Weekly, Kate's mom Carole convinced the gorgeous brunette to go out and show the prince what he was missing.

Clearly their plan worked, and the couple reunited only a few months later in July.

Even though William didn't join his future wife at the Halloween bash, we're sure that he felt like he was missing out!
