How can I make Desmond Miles's hoodie?

The simplest way to make the Desmond hoodie. Assassin's creed I'm guessing. Is to get a white hoodie and white cloth from Walmart. Then, on the cloth, make a rounded triangle and sew it to the hood of the hoodie. As for the designs, just put it on there with paint or those silver sharpies. That's how I make mine anyway. Good Luck!
