J. Crew has been putting this cashmere sweater out for a couple of seasons now, and the look is timeless, so long as you pick the right color. Some of the pastel colors, as well as some of the more vibrant ones, tend to lend this look more to around-the-house-cozy than running-errands-looking-sleek. The heather saddle and acorn are neutral and classic colors. Pair either with the Lived-in wash jeans (also by J.Crew), tall chocolate brown boots, and a green and navy scarf for a pop of color. A brown leather blazer in a similar shade to your boots will work well on cooler days.
