This t-shirt shows the love between the dark side of the moon and the light side.
On the shirt you can see a small light up part of the moon and it is getting a big hug from the dark side of the moon. And the moon is also surrounded by stars to make it look even more real.
If you always wondered what the dark side is then you are in luck because now you can see that it just a friend of the light side of the moon.
