The matching top to our sequin-embellished stripe pants, this button-down brings the same pajama-luxe formula to life: a crisp blue-and-white pinstripe poplin scattered with silver sequin floral appliqués for a shine that catches the light without feeling costume-y. A relaxed, oversized fit through the body and sleeves gives it that borrowed-from-the-boyfriend ease, while a notched camp collar and contrast black piping along the placket and cuffs add tailored, pajama-inspired detail.
