Swapping out her casual blazers and dark jeans, Kate turned heads with a glamorous purple dress -- cinched at the waist to show off her figure. Kate takes the simple frock to the next level with a diamond maple leaf brooch that was also worn by none other than the Queen herself.
For a similar style, try this Christin Michaels Noelle Wrap Dress ($89 at Zappos.com). Don't have a diamond maple leaf brooch lying around? A chunky statement necklace will kick the frock up a notch.
