JIL SANDER Jil Sander - Jil Sander's navy midi dress is made from lustrous silk satin that's undergone a washing process to give it an artfully worn look. It has a fluid silhouette, as per many of the SS20 runway pieces, and is shaped to a high mandarin collar with keyhole self-ties and long sleeves with hanging tassels, before falling to a fitted waist with godet pleats. Choose it for leisurely weekends or dress it up with minimal heeled sandals.
