While just a glimpse of the Duchess of Cambridge's short-sleeved dress by Suzannah is seen in the pictures of the royal family marveling at butterflies at the Natural History Museum in London, it's enough to predict a full-on Kate Effect.
The Budding Heart Silk Tea Dress features an empire waist and V-neckline, to ensure a flattering fit for a variety of body shapes. The knee-length frock retails for $810, or 475 pounds, and, as Tuesday, July 21, was still available in a variety of sizes on Suzannah.com. (Potential spoiler alert: It might not be available for much longer!)
Eagle-eyed Duchess style enthusiasts may recognize the dress form the royals' tour of Australia and New Zealand in the spring. There, Middleton topped the dress with a green Erdem coat for her visit to a children's hospice and war memorial on April 12.
