To wear these metallic slim - leg jeans, simply put them on like your regular jeans. They're great for casual outings or a night on the town. For a trendy look, pair them with the matching jacket as mentioned. When it comes to care, machine wash them in cold water on a gentle cycle. Avoid using bleach as it may damage the metallic finish. Hang them to dry to keep their shape. And don't iron directly on the metallic part, as high heat can cause discoloration.
