Haider Ackermann - Colombian-born, Paris fashion week stalwart Haider Ackermann's designs reflect his peripatetic childhood, as seen in this patchwork Muscari sweater. The navy and white-striped style is given a layered appearance courtesy of a knitted teal panel that covers the left side and back, creating the illusion of two pieces in one. Half-tuck it into an asymmetric midi skirt for a casual statement.
