We had previously heard that Knightley was going to walk down the aisle in a custom Karl Lagerfeld gown, the creative director of Chanel being the likely choice since the star has been the face of Coco Mademoiselle and she recently played Coco Chanel in Lagerfeld's short film Once Upon a Time, and ultimately, she did, walking down the aisle wearing a Chanel strapless, tulle dress and jacket (that was maybe inspired by her Rodarte outfit?)
It is, after all, the perfect combination
You might choose a gown with a highly traditional silhouette, such as a full ballgown, but constructed from a modern, unexpected fabric like a metallic brocade or vibrant neon silk
