The Riess Dress

Kate Middleton wore a simple belted Nanette gown by Reiss with a ruffle detail across the front for her official engagement photo taken by famed photographer Mario Testino.

If you are looking to buy the dress, you are currently out of luck as it was from the designers 2009 line. However, the designer is planning to re-release (and raise the price) of the previously discontinued Nanette dress, which originally cost $325.
