Dolce & Gabbana's suits are a stalwart of the red carpet, and this woollen navy three-piece has stellar appeal. Immaculately cut, the jacket has high armholes and a darted waist, while the legs are slim and straight for a classic silhouette. The adjustable waistcoat means you can wear it as tight or loose as you'd like and the embroidered blue pin-dots add subtle texture.
