Matching a knitted cardigan can be done by considering the color, texture, and overall style. Pair a chunky or cable-knit cardigan with slim-fitting jeans or pants for a balanced look. For a more casual vibe, wear it over a simple t-shirt or a button-down shirt. Experiment with complementary colors or opt for a monochromatic outfit. You can also layer the cardigan over a dress or skirt for a cozy yet stylish ensemble.
