Utilitarian elegance is a 3.1 Phillip Lim rite of passage and it's something that we see in full force with this midi dress. It cinches at the waist with a D-ring belt - a detail that's often found on the label's military-charged jumpsuits - and features knotted sleeves that have become quite the House signature. To complete the look, offset the pine green hue with a pastel pair of sandals.
