To use this tee, simply put it on like any other shirt. It's great for daily wear, workouts, or any casual activity. When it comes to washing, use cold water and mild detergent. Avoid using bleach as it may damage the fabric. Hang it to dry or tumble dry on low to keep it in good shape. For long - term storage, fold it neatly and keep it in a cool, dry place. Enjoy your comfortable and stylish tee!
