White cotton blend and silk lace dress featuring delicate pleats, a high neck, three-quarter sleeves, a concealed rear zip fastening and a flared skirt. By Alexander McQueen.
The dress worn by the Duchess is a bespoke piece with a higher neckline and a longer hem. It is a lovely dress but I prefer the version with the round neck.
1- The Duchess of Cambridge wore this white lace dress on 20th June 2017 when attending Royal Ascot.
