Sies Marjan's creations are best defined by a fervent sense of femininity, expressed through fluid shapes and vivacious color schemes. We think there's a beautiful lightness to the label's designs, making them perfect for capturing an optimistic and free-spirited feel all year round.

New York-based, Dutch-born and Central Saint Martins-educated designer Sander Lak began his fashion career at Dries Van Noten, which set him in good stead to launch his own label in 2016. Instead of choosing to launch an eponymous brand, Lak instead derived his new venture's name by combining the first names of his father, Sijes, and mother Marjan.
