This T - shirt is super easy to use. Just put it on and show off your love for dogs! When it comes to maintenance, it's machine - wash safe. So you can simply toss it in the washing machine with your regular laundry. Use a gentle cycle to keep the fabric in good shape. For the colors, especially the heather ones which are a blend of cotton and polyester, they should stay vibrant for a long time. Remember, the preview images might look a bit different from the real T - shirt in color, so don't be surprised if there's a slight variation. Enjoy wearing your personalized dog - themed T - shirt!
