To use this tee, simply put it on and go about your day. It's great for casual outings or activities by the lake. When it comes to washing, use cold water and mild detergent. Tumble dry on low to keep it in good shape. Avoid using bleach as it may damage the fabric and the graphic print. Hang it to dry if you want to be extra gentle. Store it in a cool, dry place to prevent any mildew or damage.
