To use this t - shirt, simply put it on like any other shirt. It's great for casual outings or just lounging at home. When it comes to washing, you can toss it in the washing machine on a gentle cycle. Use mild detergent to keep the fabric and colors in good condition. Avoid using bleach as it might damage the anti - bacterial treatment and the fabric. Hang it to dry to prevent shrinkage. Store it in a cool, dry place, and it'll be ready for you to wear again whenever you want.
