How to Dress Like a Ninja Using Only a T Shirt

Want to become a ninja using only a t-shirt? Easy enough, with this simple solution.

Steps

Use whatever color T-Shirt you like; T-shirts without logos work easier.
With the sleeves at the sides, bring the T-Shirt over your head until the collar rests at the top of your head.
Rest the back of the collar at your forehead, just above the brow line, and the front of the collar on your nose.
Bring the sleeves around to the back, and tie them off.
Make any adjustments to fit properly and comfortably. Hide all tags and logos (if applicable).
Make sure the hood covers all but the area between eyebrows and the bridge of the nose. If you don't do this you could hit a wall.
Now
Get a black sweater with a hood and put the hood over your head. Also wear black pants.
