To use this sweater, simply slip it on over your head and adjust it to your liking. It's great for casual outings like going to the park, meeting friends, or running errands. When it comes to washing, it's best to use a gentle cycle in cold water to keep the colors vibrant and the fabric in good shape. Avoid using harsh detergents as they might damage the acrylic material. After washing, lay it flat to dry instead of hanging it, which can cause the sweater to stretch. And don't forget to check the size chart before buying to ensure you get the right fit for a comfortable wearing experience.
