A crisp white button-down from R13, cut in the label’s signature oversized proportions with dropped shoulders, a single chest pocket, and a cropped, curved hem. Joanna owns the same shirt in light blue, but this one never made it into rotation. “I have so many white shirts, I didn’t even manage to touch it,” she says. What she loves is the abbreviated length: “You can dress it really nicely with high-waisted pants—elegant or jeans, whatever you prefer.”
