This single breasted blazer, from M&S, is cut from cotton with a small amount of elastane for a touch of give through the shoulders and arms. The shawl lapel and lined construction give it a smart, occasion ready finish suited to parties and evening events. A slip pocket at the front adds a practical detail without disrupting the clean lines of the jacket, and the long sleeves keep the silhouette classic. M&S Collection: easy to wear wardrobe staples that combine classic and contemporary styles.
