What is a shawl collar cardigan good for?

It covers the neck and chest more than a V-neck cardigan, so it works as a warm middle layer over a tee or thin turtleneck. The open front lets you adjust how much warmth you keep.

How does the loose fit run?

It is cut loose and relaxed, so it layers over other tops without pulling. If you want a closer fit, consider a size down.

The knit fiber is not specified. Check the item's label or material details before buying, since blends of acrylic, wool and cotton behave differently in washing and warmth.

Is a pre-owned knit cardigan a good choice?

It can be, since knit layers are simple garments with few failure points. Inspect for pilling, stretched cuffs and missing buttons, which are the usual signs of wear.

How should I wash it?

Hand wash or use a gentle cycle in cold water and lay flat to dry to keep the knit from stretching. Avoid hanging it wet, which distorts the shoulders.
