Embrace Polo Ralph Lauren's preppy sensibility with this collegiate cardigan from the American label. Crafted from cotton knit, the V-neck style has an oversized fit and striping at the sleeve. But our favorite details are the varsity-style "R" appliqué at the chest and the number "67" at the pocket, nodding to the year the brand was established. Layer yours over denim and tailoring alike to infuse a sense of country club cool into your ensembles.
