In need of an easy shot of cool? Think leather. Take a page from blogger Mija Knezevic, who uses dark leather as a chic counterpoint. She toughens up the casual and sporty vibe of her baseball jacket-and-tee combo with our Ally Leather Pant, for instance, and pairs a leather LBD with our ladylike Katie Mohair Coat for some added edge. She adds a touch of eccentricity with embroidered cowboy boots and printed loafers.
