To use these DC youth crew socks, simply put them on like you would any other socks. They're great for everyday wear, whether you're going to school, playing sports, or just hanging out. As for care, it's best to machine wash them in cold water with like colors. Avoid using bleach as it can damage the fabric and the logo. Tumble dry on low to keep them in good shape. If you notice any loose threads, you can carefully snip them off. These socks are built to last, but with proper care, they'll look and feel great for a long time.
