Actually I didn't use any materials for the hoodie. The hoodie is a plain simple black hoodie with a zipper. What really transforms this hoodie is the matryoshka smile and eyes on the sides. But this hoodie is made out of cotton, so hope this helps you!.
My friend made it for me. There are a bunch of various designs since it's an AU and people have their own interpretation of how the design should be. So my friend just made her own version which I used.
It's just a simple black cotton hoodie. You can easily buy one and put the matryoshka smily and eyes on the sides. That's what really makes the difference. I would have sewn this, but since I planned it 1 week before a convention I had to act quick.
