Simon Lewis is known for his general goofiness and his spunky t-shirts.

On The Mortal Instruments: City of Bones set yesterday, Robert Sheehan was photographed wearing the MADE IN BROOKLYN t-shirt described in the books. Soon after, Cassandra Clare told fans on Tumblr where they too could buy the graphic tee!

The design comes from Brooklyn Industries and is available online for $34!

Would you ever buy yourself this tee or one of Simon’s other quirky slogan shirts?
