Spectacular c.1978 Valentino Blue & Coral Floral Silk Halter Backless DressThis is the exact dress that Martha Hunt wore to the Cannes Film Festival in 2018. Amal Clooney also wore a more graphic print version of this dress at one point in a different print and colorway. Hers was more graphic and did not have the same ruffles and softness that this one does. I think this floral one is just the prettiest thing I have ever seen. The dress is spectacular and even landed Martha in the Harper's Bazaar round up of the best looks
