To wear this shirt, simply put it on like you would any other shirt. It's great for casual outings or for showing your love for Beastie Boys. When it comes to washing, you can toss it in the washing machine on a gentle cycle with cold water. Use a mild detergent to keep the colors vibrant. Avoid using bleach as it can damage the fabric. Hang it to dry or use a low - heat setting in the dryer. This shirt is made of 100% cotton, so it might shrink a bit if you use high heat. Iron it on a low - heat setting if needed, but be careful around the printed graphics on the front and back. Enjoy wearing your Beastie Boys shirt!
