To use this cardigan, simply layer it over your favorite shirts or blouses. It's great for transitional seasons when the weather is a bit unpredictable. As for care, you can machine - wash it on a gentle cycle with like colors to keep it soft. Avoid using bleach as it might damage the cotton fleece. Hang it to dry to prevent shrinking. And when not in use, fold it neatly and store it in a cool, dry place to maintain its shape.
