You really have to see the attention to detail on Brunello Cucinelli's clothes to believe it – the label's Umbrian HQ even has special equipment to analyse the quality of every cashmere piece, while each pair of jeans is checked over by a denim specialist before being signed off. Knitted in Italy from cotton blended with touches of linen and silk, this sweater is edged with striped ribbing to keep the neat stitches from unravelling.
