Sablyn's 'Reign' cardigan can be worn on its own as a shirt, or with a few buttons undone over an equally slim-fitting tank. It's knitted from lightweight cashmere in a rich petrol hue and has a polo-inspired pointed collar. Wear it as a set with the matching pants. -- Petrol cashmere - Button fastenings through front - 100% cashmere - Dry clean - Designer color: Topaz
