Cardigan sets are typically sold as two-piece or three-piece combinations. Two-piece sets pair a cardigan with a tank or camisole; three-piece loungewear sets add matching pants to the cardigan and top.
Pocket details vary—some cardigans include one or two functional front pockets (occasionally with button accents), while others have no pockets. Closure styles include open-front cardigans and pullover-style tops (no front closure).
Most sets are polyester-based, including plain polyester and blends such as 63% polyester/37% viscose, 95% polyester/5% spandex, 97% polyester/3% spandex, and poly/rayon/spandex blends.
Cardigan lengths vary from at-waist to below-hip and, in some styles, below the knee—one listing notes a 34" cardigan length. Matching tops range from cropped lengths up to about a 30" tank length.
