A good turtleneck is the ultimate wardrobe building block in colder months. Of course you can wear it solo, but as a base layer, it'll give some extra (and seasonally-appropriate) life to dresses, sweaters, shirts, you name it. Ours has a trim fit, with a neck that can be either folded or scrunched, and it's made of pima jersey that's lightweight enough to layer, but substantial enough to stand on its own. Pima's like the cashmere of cotton. It only gets softer — without pilling, without clinging — the more you wear it.
