Well, it seems this big sis wasn't having any of it!

In 2007, during a time when she and William were broken up, the 25-year-old Kate donned a glittery black dress, knee-high boots, and a cape for Halloween. The future Duchess of Cambridge looked stunning in a sexy witch costume as she sashayed out into the night with her sister, Pippa Middleton.
Well, we're sure William felt remorseful when he saw Kate's hot Halloween pics!
It's just crazy to think that just a few years ago the Duchess was trying to win her now husband back with a sexy Halloween costume!
See, the royals are really just like the rest of us!
