This week we have a ladylike line-up, with Delfina Delettrez looking perfect in Fendi and Keira Knightley looking 50s-housewife-in-a-good-way in Orla Kiely. Olivia Palermo quietly sparkles in Valentino, and Alessandra Ambrosio is covered up and pretty in seafoam Missoni. Finally, Elisa Sednaoui channels a flapper in Louboutin and a headband.
