Using this shirt is a breeze! Just put it on like any other shirt. It's great for casual outings like hanging out with friends or running errands. When it comes to care, it's best to machine wash it in cold water on a gentle cycle. This will help keep the holographic print looking vibrant. Avoid using bleach as it can damage the fabric and the print. After washing, tumble dry on low heat. If you need to iron it, set your iron to a low - heat setting and iron on the reverse side of the shirt to protect the print. Also, make sure to check the size chart carefully before buying to ensure you get the right fit for maximum comfort.
