A cardigan opens in the front with buttons or a zipper, making it easy to put on and remove like a jacket — ideal for layering and temperature regulation. A sweater (pullover) is a closed garment pulled over the head, offering a cleaner silhouette and slightly more polished look. The key difference is the front opening: cardigans offer flexibility, pullovers offer simplicity.

Frequently Asked Questions
Is a cardigan or pullover sweater more versatile?A pullover sweater is more versatile in most wardrobes. It has a cleaner silhouette, works standalone or under blazers, and looks polished with minimal effort. A cardigan adds layering flexibility but requires more intentional styling to avoid looking frumpy.
Can you wear a cardigan to the office?Yes — a fine-gauge cardigan in merino or cashmere over a dress shirt is a professional alternative to a blazer. Avoid chunky, oversized, or patterned cardigans in formal offices. Navy, charcoal, and gray are the safest office colors.
Is a cardigan considered a sweater?Yes. A cardigan is a type of sweater — specifically, an open-front sweater with buttons or a zipper. When people say 'sweater' without qualification, they usually mean a pullover (closed, over-the-head) style.
What type of cardigan is most flattering?A fine-gauge V-neck cardigan that hits at the hip is the most universally flattering. It creates a vertical line that elongates the torso. Shawl-collar cardigans add visual width to the chest, which flatters slim builds but can overwhelm larger frames.
Should a cardigan be buttoned or unbuttoned?Both work depending on the context. Buttoned (with the bottom button undone) looks more intentional and polished. Open/unbuttoned works for casual layering. Avoid buttoning all buttons — it creates a boxy, constricted look.
What's the difference between a cardigan and a jacket?A cardigan is knitted knitwear with a soft drape. A jacket is woven fabric with a structured construction (seams, lining, defined shoulders). Cardigans are lighter, softer, and more casual than jackets, though some thick cardigans can substitute for light jackets in mild weather.
