Los Angeles label Co has built its brand on carefully considered pieces, such as this black shirt dress – equal parts classic and modern. Crafted from cotton, the design has a slim-fitting, short-sleeved bodice with a self belt at the waist. It falls into a full, midi-length skirt with a stepped hem that dips dramatically at the back. Wear yours with contemporary ballet flats and a color-blocked handbag for a look that captures the label's coolly elegant character.
