La Collection's co-founder Florence Cools has used the word 'sober' to describe the label's color palette - her and Artur Tadevosyan are usually photographed wearing white or black. This 'Jacqueline' dress from the Spring '19 lineup is made from silk-satin in the latter shade and has been tested up to 20 times to ensure it fits perfectly and feels lustrous. The midi length is really chic, too.
