What is is a cardigan a jacket?

A cardigan is not quite the same thing as a jacket. While both types of clothing can be worn to provide warmth, jackets are typically more structured and made from heavier materials, like leather or denim. Cardigans, on the other hand, are lightweight and often made from softer materials like cotton or wool. Additionally, cardigans are typically designed with an open front and button or zip closures. They are often used as a layering piece or a fashion accessory, whereas jackets may be worn as a primary outer layer.
