An androgynous blazer never goes amiss in any well-equipped style edit, and we're turning to Saint Laurent's this season. Comprising a sumptuous fusion of soft wool and alpaca fibers, the Italian-made design has been rendered in black and white glen plaid and, for heightened modernity and an uninterrupted silhouette, its placket comes button-free. Opt for a monochromatic look from head to toe, styling yours with a white blouse, a black leather miniskirt and matching ankle boots.
