Simple and Easy. I am not a fan of Muscle tee but I am bored and I want to kill some time. This is very short blog post because it is very easy, and doesn't need a lot of effort to do.
What you will need?
T- shirt (Printed or Plain)
Scissors
Lay down the Tshirt in a flat surface.
Simply trace the Broken Line and Viola! It's Done! You can have the new trend in the Fashion world. P.S. Make sure to pull out the threads in the armhole.
