Sleeveless nude dress by Joseph called the “Vanessa dress” .Sleeveless crepe scoop-neck shift dress with gros grain trim belt. It is gathered to the waist, features flat seam trim and fastens with a gros grain covered zip to the rear.
I love this dress I really want to make a similar one for me but maybe in a more luxurious looking fabric as this one looks a bit flimsy, but I love the cut and style of the dress and Kate wears it perfectly.
1- The Duchess of Cambridge wore it on 3rd July 2011 at Québec City, and she wore it later on during the day arriving at Charlotteville airport with a pale pink tweed jacket and a different (and more elegant in my opinion) pair of shoes.
2- Kate wore again the dress on 8th July 2012 at Wimbledon to watch a tennis match. She wore it underneath the Nessie Tweed Jacket also by Joseph.
