A rib-knit cardigan with a tall funnel collar that buttons right up under the chin, which is the difference between a cardigan you wear indoors and one you can walk out in. Buttons run the full length of the front, so the collar can stand closed against the wind or fold open into a soft V when you are inside. The rib runs fine and even from collar to hem, so the surface stays consistent.

Raglan seams take the sleeve up into the neckline instead of cutting across the shoulder, which is why it sits comfortably under a coat and why the shoulder never feels bound. The body is shaped gently through the waist and the hem steps down slightly at the front, breaking the straight line where it lands. It works over a shirt as readily as over a tee, and under a coat without a collar getting in the way.
