This weekend in Scotland, Pippa Middleton attended Camilla Hook and Sam Holland's wedding in a familiar-looking dress. I did a double take when I saw Pippa in a raspberry version of her sister, Kate Middleton's Issa Forever dress. The Duchess of Cambridge wore the £475 silk jersey dress in sapphire back in November 2010, for the announcement of her engagement to Prince William. Pippa accessorised the wrap dress with a corsage-covered black fascinator, envelope clutch and black heels. Which Middleton sister wore it best?
