This is the “Addison” multi azure printed silk dress with its jewel-toned print, sheer long sleeves and ankle grazing length. By the British brand L.K. Bennett.
I partly like this dress and I partly dislike it. I like the material, the length, the effect it gives when it is worn. But I am not too keen on the print, and it looks a bit old-fashioned when it is worn by the Duchess.
1- Kate wore this dress on 22nd April 2016 for a dinner with Michelle and Barack Obama at the home of the Duke and the Duchess of Cambridge in Kensington Palace, London.
