Here's the hoodie that you wanted, although this is fitted to Koyuki's base instead but same thing anyways.

These look better to me but the best hoodies already come with an avatar so if you find an avatar with a hoodie you like on booth, link it and I'll see if I have the avatar and can just upload the hoodie alone. I'll only upload one thing so choose wisely.
