Browsing a bookstore aisle by aisle, pulling a title off every shelf, looks effortless in the Marine Layer Ivy Cable Knit Polo, a collared sweater with a polished edge. The oversized scalloped collar frames the neckline, while the cotton-rich cable knit and delicate rib add texture that holds its own without a statement piece. This cable knit polo sweater runs fitted and hits at the high hip, and it stays light enough to slide under a jacket.
