This is Sleepy Jones’s foundational pajama set: They’re cut from crisp, soft cotton that’s light and breathable. The tailored top has an easy fit through the body, full-length sleeves, and a hem that hits right at the hip. The pants are cut straight, with an elastic waist and full-length legs. They’re finished with piped trim throughout—and plenty of pockets (one at the chest, two at the sides, and two in back).
