Joanna bought these ivory Blumarine trousers at the house’s Milan boutique more than eight years ago. Cut in a crisp cotton blend, they feature an allover geometric eyelet pattern and a dramatically wide leg, with lining through the upper portion before becoming sheer below the knee. “Down to the knee, they have coverage,” Joanna explains, “and then they’re a little see-through on the calf.” The result is airy without feeling overly revealing.
