Kate Mouse Tee; Net A Porter $80, Me, Free! :)

This was actually very easy, I don't think I need to make a how-to.
Basically you find any graphic tee or image and blow it up really big on a computer.
Next you get some paper and trace over it.
Third, get a plain shirt made of thin or light colored material and place the paper with the design underneath.
Finally, trace onto the shirt with fabric markers!
