Royal clothing swap!

Pippa Middleton, 28, stepped out for a friend's wedding in Suffolk, England this past weekend in an elegant Katherine Hooker coat, which happens to be the same $1,125 jacket that her sister, the Duchess of Cambridge, wore for her first public engagement in Wales last February.

The hot British bachelorette styled the velvet-adorned jacket with gray suede pumps and a matching clutch by Emmy Shoes, plus chandelier earrings and an eye-catching hat, while 29-year-old Kate paired it with brown tights, a scarf and a coordinating feather topper.
