Named after the renowned 20th-century artist, Haider Ackermann's Prussian-blue silk-satin Dali blouse is the perfect anchor to modern evening looks. It's cut to an oversized silhouette with a neat band collar and finger-skimming sleeves, and falls into a step hem – perfect for tucking into high waistlines. Style it with tailored trousers and backless loafers for a casual-luxe feel.
