A ribbed polo collar opens into a two-button placket on this knit polo sweater, giving the neckline a relaxed, undone finish. The dropped shoulders and softly oversized body let the sleeves taper into ribbed cuffs for a slouchy, easy line. Ribbing at the collar, placket, and hem contrasts with the smooth knit body, adding texture without bulk. Long sleeves and a straight hem make it easy to wear tucked or loose for weekend or transitional layering.
