Joanna bought these crisp white cotton Jil Sander trousers at the house’s NorthPark boutique in Dallas about two years ago. Cut with deep pleats and an exaggerated wide leg, they feature an elasticated drawstring waist and button-trimmed ankles that punctuate the otherwise minimal silhouette. Barely worn, they’re a particularly good example of Jil Sander’s knack for turning the simplest pieces into exercises in proportion.
