How to use: You can wear this T - shirt whenever you want, whether you're going to the gym, having a casual day at home, or doing some light exercise. Just slip it on and you're good to go! Things to note: Before purchasing, make sure to check the size chart as the T - shirt has a slim fit and runs 1 - 2 sizes smaller than regular. Also, keep in mind that the color you see on your monitor might be a bit different from the actual shirt. Maintenance: You can machine - wash this T - shirt in cold water. It's best to turn it inside out before washing to protect the 3D painted design. Hang it to dry to keep its shape, and avoid using bleach.
