To wear this cardigan, simply slip it on over your outfit. It can be worn open for a laid - back look or closed and belted for a more put - together style. When it comes to cleaning, check the care label. Usually, it's best to hand - wash it in cold water with a mild detergent to keep the crystals in good condition. Avoid wringing it out. Lay it flat to dry. Keep it away from sharp objects to prevent damage to the crystals.
