cardigan

This garment is characterized by its versatility as a layering piece, occupying a middle ground between a formal jacket and a casual pullover. It evokes a sense of comfort, domesticity, and often a scholarly or conservative aesthetic, frequently associated with academic or home environments.

Because it is a discrete physical object, it follows standard English countability rules. It is a common count noun that can be quantified with numbers or indefinite articles, and it forms its plural by adding a standard suffix.
