It's not quite full-on sweater weather yet, and this in-between season calls for layers that feel light yet cozy (and endlessly versatile). On days with brisk mornings and warmer afternoons, knit tops, vests and cardigans are the ultimate solution. They create a polished, put-together vibe while still keeping you comfortable when the temperature outside just can't make up its mind. Amazon is stacked with chic transitional knits that look way more luxe than their price tags.
