To use this tee, simply put it on and go about your day. It's great for casual outings, workouts, or just relaxing at home. When it comes to washing, use cold water and a gentle cycle. You can tumble dry on low to keep it in good shape. Avoid using bleach as it may damage the fabric and the graphic print. If you need to iron, set your iron to a low - heat setting. This tee is made to last, so with proper care, you'll enjoy it for a long time.
